ENGINE

The Ninja ZX-4RR KRT Edition boasts an all-new 399cc liquid-cooled, 4-stroke, in-line four cylinder engine that delivers exhilarating performance and fun-to-ride power. Developed with feedback from other Kawasaki Ninja ZX supersport machines, the all-new engine found on the Ninja ZX-4RR KRT Edition features a quick-revving nature with a direct throttle response that combines strong low-mid range torque for city riding and high-rpm power that can be enjoyed when riding on the track. As riders roll on the throttle, they are rewarded with a satisfying surge of acceleration that is complemented by the distinct intake and exhaust notes of a Kawasaki in-line four cylinder engine.

The liquid-cooled, DOHC, 16-valve, 399cc in-line four cylinder engine features a bore and stroke of 57.0 x 39.16mm and packs impressive power and strong torque. The bore and stroke contributes to the impressive top-end power. A high-spec ECU is similar to that found on the Kawasaki Z H2, which allows for the use of Kawasaki’s latest electronics. Electronic Throttle Valves (ETV) with 34mm throttle bodies provide smooth, natural engine response by enabling the ECU to control the volume of both the fuel (via the injectors) and the air (via throttle valves) delivered to the engine. Additionally, they facilitate the use of Kawasaki electronic rider support systems such as integrated riding modes with traction control, selectable power modes, and a dual-direction Kawasaki Quick Shifter (KQS) that allows riders to feel “at one” with their machine.

Intake port interiors are sand cast using fine sand, which results in a smooth finish. Similar to the Ninja® ZX™-10R, the intake port exits have been machined in two stages, first along with the valve seats and then again at an inclined angle, to create a straighter path for intake air as it enters the combustion chamber. The straighter and wider path for the intake air promotes a smoother flow and a greater volume of fuel-air mixture that contributes to the engine’s high performance. Lightweight forged camshafts contribute to the high-revving and high-rpm performance.

Large 22.1mm intake valves are complemented by 19mm exhaust valves, flowing a great volume of air for excellent high-rpm performance. Triple-rate valve springs accommodate the valves and add to the Ninja ZX-4RR KRT Edition’s high-rpm performance. A narrow valve angle helps combustion efficiency as well as achieves a compact engine design. The combustion chambers are precision machined to high tolerances – a production technique that is limited to Kawasaki’s high-performance premium models.

Lightweight cast aluminum pistons contribute to low reciprocating weight for quick-climbing revs. The piston skirts have a molybdenum coating that increases durability. The piston crowns were designed to develop compression, which contributes to the 12.3:1 compression ratio that is found on the Ninja ZX-4RR KRT Edition and optimized to allow the use of regular gasoline while achieving strong performance. The piston’s wide bore facilitates the use of the large intake and exhaust valves for greater air flow, while their short stroke adds to the high-rpm performance. Utilizing an aluminum die-cast cylinder with an open-deck design, excellent heat dissipation and low engine weight is achieved.

In order to reduce mechanical loss and vibration, Kawasaki engineers carefully selected the connecting rod ratio, while a special carburizing treatment was used on the connecting rods to improve durability and reduce weight. Thanks to the crankshaft’s light flywheel mass, a low moment of inertia was reached, contributing to a quick-revving engine character and direct throttle response. A deep oil pan ensures that the oil pump inlet is always submerged, blocking air from being ingested, even during hard acceleration and deceleration while sport or track riding.

ADVANCED ENGINE COOLING

With the Ninja ZX-4RR KRT Edition engine designed for high performance, Kawasaki engineers placed a great emphasis on the engine’s cooling system in order to achieve optimum performance. The water jackets on the cylinder head were carefully designed and long-reach spark plugs offer greater contact with the water jacket, helping to prevent engine knocking. A large, 30-row radiator provides efficient engine cooling to handle the Ninja ZX-4RR KRT Edition’s performance capabilities. Side air ducts are built into the fairings to direct cool air towards the engine and promote heat dissipation that greatly contributes to engine performance. Innovative Kawasaki technology like the patented radiator fan cover that is located behind the radiator directs hot air out to the sides and away from the rider, improving rider comfort. The heat management system was designed using CFD analysis and controls the flow of air, helping keep the tank, frame, and other parts that contact the rider cooler, further increasing rider comfort.

RAM AIR DUCT INTAKE SYSTEM

The Ram Air duct system is a trademark feature on Kawasaki’s Ninja ZX models. It’s a centrally positioned intake that improves filling efficiency and increases engine performance. Following a layout that is similar to that of the Ninja H2, the Ram Air duct is routed to the left of the front fork on its way to the airbox. This contributes to a duct with a highly efficient airflow, enabling cool, high-pressure air from the front of the bike to be ingested. Engine performance is increased at all rpm thanks to the increased pressure and cooler air. Additionally, the design is extremely effective at preventing water from entering the airbox while riding in the rain. The large Ram Air duct has “Ram Air” stamped into it, which is visible to the rider and adds to the Ninja ZX-4RR KRT Edition’s high-performance look and feel. Intake funnels, consisting of 60mm and 40mm lengths, contribute to efficient filling and produce a flat torque curve with smooth power delivery. The downdraft intake creates a shorter, more direct path for intake air to enter the cylinder, improving cylinder-filling efficiency and increasing engine power, especially at high rpm.

EXHAUST

The header pipes and collector pipe layout were built with inspiration from the Ninja® ZX™-6R. Joint pipes link the headers, contributing to a strong power output while meeting emissions and sound regulations. A traditionally styled, long silencer produces a clear, racy exhaust note that is distinct to that found on a Kawasaki in-line four cylinder engine. The collector pipe features triple catalyzers to ensure emissions are met and their position makes it easy to add a slip-on muffler.

TRANSMISSION & CLUTCH

Complementing the high-performance 399cc engine is a smooth-shifting six-speed transmission that is designed to shine in all riding situations. It’s especially well suited for riders accelerating out of corners when sport or track riding and features a dual-direction Kawasaki Quick Shifter (KQS). Developed through Kawasaki’s racing efforts, the Ninja ZX-4RR KRT Edition is fitted with an Assist & Slipper Clutch that uses two types of cams (an assist cam and slipper cam), offering two functions that are not available on a standard clutch. When the engine is operating at normal rpm the assist cam functions act as a self-serve mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, resulting in a lighter clutch lever pull when operating the clutch. When excessive engine braking occurs, the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back torque and help prevent the rear tire from hopping or skidding.

ELECTRONICS

KAWASAKI TRACTION CONTROL (KTRC)

Kawasaki’s advanced KTRC system provides both enhanced sport riding performance and peace of mind under certain conditions to negotiate low-traction surfaces with confidence. Three selectable modes offer progressively greater levels of intrusion that cut fuel and ignition to help maintain traction and forward drive as well as suit the riding situation and rider preference. The system uses a number of parameters to get an accurate real-time picture and adapt accordingly. Mode 1 is the least intrusive and designed with sport riding in mind, Mode 2 intervention occurs earlier offering a balance of sport riding support and rider confidence, and Mode 3 is the most intrusive for navigating low-traction conditions. In addition to the three modes, the rider can elect to turn the system OFF.

POWER MODES

Power Modes offer riders an easily selectable choice of engine power delivery to suit riding conditions or preferences. In addition to Full Power mode, one (Low) alternate mode in which maximum power is limited and throttle response is milder is provided.

INTEGRATED RIDING MODES

All-inclusive modes that link KTRC and Power Mode allow riders to easily set traction control and power delivery to suit a given riding situation. Riders can choose from three settings (Sport, Road, Rain) or a manual setting (Rider). In the manual Rider mode, each of the systems can be set independently.

KAWASAKI QUICK SHIFTER (KQS)

Adding to its impressive list of high-performance features, the Ninja ZX-4RR KRT Edition comes equipped with dual-direction KQS. The KQS allows ultra-quick upshifts and downshifts without the need to use the clutch, resulting in a more enjoyable experience and quicker lap times. Designed for more effective sport riding, KQS can also be used on the street when the engine is above 2,500 rpm.

TFT COLOR INSTRUMENTATION

The 4.3” all-digital TFT color instrumentation gives the cockpit a high-tech, high-grade appearance and features a Circuit Mode that allows lap timing and shows track-related information in a more prominent and easier-to-view layout. The high-grade color LCD screen features TFT (thin-film transitory) technology, delivering a high level of visibility. Selectable background and text colors can be chosen to suit light or dark conditions and screen brightness automatically switches between five levels to suit available light.

Display functions include a digital speedometer, digital bar-style tachometer, gear position indicator, shift indicator (tachometer flashes), fuel gauge, odometer, dual trip meters, current and average fuel consumption, remaining range, average speed, riding time, coolant temperature, clock, battery voltage, lap timer (Circuit Mode only), Kawasaki service reminder, oil change reminder, integrated riding mode, KTRC and power mode indicators, smartphone call and mail notices, Bluetooth indicator, economical riding indicator, and KQS indicator.

Circuit mode can be toggled for use at track days and changes the display to make information for track riding more visible. This includes showing the lap time in the center with large text so that it can easily be ready while riding. The gear position and tachometer display is also more visible along the top when above 10,000 rpm, giving riders a clear view of the information needed when working towards faster lap times on the track.

RIDEOLOGY THE APP

Bluetooth® technology built into the instrument panel enables riders to connect to their motorcycle wirelessly. Using RIDEOLOGY THE APP*, a number of instrument functions can be accessed, logged, and reviewed contributing to an enhanced motorcycling experience. The following information can be viewed:

Vehicle Info – Information such as fuel gauge, odometer, maintenance schedule and more can be viewed via the smartphone
Riding Log – GPS route information as well as vehicle running information can be logged and viewed via the smartphone
Mobile Phone Notices – When a call or email is received by the smartphone, this is indicated on the instrument display
Tuning / General Settings – General instrument display settings such as preferred units, date, date format, and more can be adjusted via the smartphone

The app can also be used when away from the motorcycle. When riding (with the app ON), the bike and smartphone are always connected and riding log data is being recorded by the app. After your ride, the latest riding information is stored by the app and may be viewed on the smartphone. Any changes made via the app while the engine is off, or while out of range, will be implemented as soon as the ignition is turned on and the smartphone is in range with the app ON.

* RIDEOLOGY THE APP is not intended for use during vehicle operation. Only use RIDEOLOGY THE APP when the vehicle is not being operated and it is safe to do so.

CHASSIS

The Ninja ZX-4RR KRT Edition delivers light maneuverability when riding around town, however, its high-level supersport character shines when out sport riding on backroads or at the racetrack. Utilizing feedback derived directly from Kawasaki Racing Team’s (KRT) efforts in the FIM World Superbike Championship, Kawasaki engineers carefully selected key chassis components to achieve excellent rigidity balance. Formed from high-tensile steel, the trellis frame features various pipe diameter thicknesses with a swingarm pivot section. Kawasaki’s advanced dynamic rigidity analysis was used to ensure the required balance of strength and chassis flex.

Key chassis dimensions, such as center of gravity position, swingarm pivot position, engine axis positions, and the caster angle were inspired by Kawasaki’s World Superbike Ninja® ZX™-10RR, bringing World Superbike chassis design to the 400cc class. The long-style swingarm is made from high-tensile steel and allows the bike’s front-rear weight distribution to be set for the perfect balance of nimble handling and composed chassis behavior. An arch design on the right side of the swingarm delivers the required balance of rigidity and flex, enabling the silencer to be positioned as centrally as possible while adding to the Ninja ZX-4RR KRT Edition’s stylish, sporty looks.

SUSPENSION

To complement the optimal rigidity balance of the chassis, the Ninja ZX-4RR KRT Edition front end is held up by a 37mm inverted front fork that features Showa’s SFF-BP (Separate Function Fork – Big Piston) technology. This advanced fork offers both racetrack performance and everyday usability. The technology is similar to that on the Ninja ZX-6R, while the spring rate and damping characteristics were developed specifically for the Ninja ZX-4RR KRT Edition. The front fork provides smooth action at the initial part of the stroke that contributes to excellent composure under braking. A large-diameter damping piston is used in the SFF-BP fork, which is much larger than that used in a cartridge-type fork. This allows oil inside the fork to act on a much larger surface area and damping pressure to be reduced while ensuring the same damping force. By reducing the damping pressure, it allows the slide pipe to move more smoothly, which is especially noticeable during the initial part of the stroke. This design allows for greater control as the fork begins to compress and a smooth transition as the Ninja ZX-4RR KRT Edition’s weight shifts forward when reducing speed, offering greater chassis stability on corner entry and a planted feel when braking. The fork settings were designed to accommodate a wide range of riding situations, from the city to the racetrack. The spring preload is adjustable and can be tailored to suit the rider’s preference, which is the first use of adjustable SFF-BP in the 400cc class.

At the rear of the Ninja ZX-4RR KRT Edition, horizontal back-link rear suspension mounted to a Showa BFRC (Balance Free Rear Cushion) Lite shock can be found. The shock is similar to that found on the Ninja ZX-10R and has been specially tuned for the Ninja ZX-4RR KRT Edition. Its excellent movement at the start of the stroke ensures comfort in day-to-day riding as well as a planted feel when riding on the track, while linear damping characteristics provide a stable, solid feel and peace of mind for the rider in a wide variety of situations. Additionally, it offers adjustable compression and rebound damping as well as adjustable spring preload so that riders can fine-tune the rear end to suit their riding preferences. The horizontal back-link rear suspension positions the shock unit and linkage above the swingarm and out of the way from engine and exhaust heat. A firm rear shock feel achieves a planted feel that is reassuring during sport riding, while also offering ample absorption for ride comfort when riding around town.

WHEELS & BRAKES

In order to stop the powerful Ninja ZX-4RR KRT Edition, a pair of 290mm semi-floating front discs handle the stopping duties up front and are gripped by 4-piston radial-mount monobloc calipers. The calipers feature different diameter pistons with the upper piston measuring 32mm and the lower piston 30mm. Dual front discs were chosen for additional stopping power and the monobloc calipers help achieve a firm initial touch. Brake pad selection contributes to both brake force and braking controllability.

At the rear, a 220mm disc is slowed by a single-piston caliper that is powered by a 38mm piston. The master cylinder, caliper, brake pedal, and brake pad material were carefully selected for a balance of stopping power and control. Equipped with ABS, the Ninja ZX-4RR KRT Edition features Nissin’s latest ABS control unit that has been specially developed to deliver precise control and is the most compact and lightweight unit available.

Stylish star-pattern five-spoke wheels contribute to the bike’s overall lightweight and their high rigidity improves handling. The wheels also contribute to the bike’s light, nimble appearance. Dunlop Sportmax® GPR-300 radial tires are mounted on the front and rear, offering high grip in both wet and dry conditions and contributing to agile handling and excellent riding comfort. A 120/70ZR17 tire is used on the front and 160/60ZR17 is fitted on the rear.

ERGONOMICS

To take full advantage of the Ninja ZX-4RR KRT Edition’s nimble, supersport-style handling is a naturally aggressive riding position that is more forward-leaning than that found on the Ninja 400. The riding position on the Ninja ZX-4RR KRT Edition offers a good balance of wind protection and aerodynamics that enable the rider to tuck in to get out of the wind, while still maintaining a relaxed feel. A slim design of the fuel tank between the rider’s legs promotes good contact with the bike and a low design on the top of the fuel tank facilitates the rider getting into a tucked position. A firm seat cushion offers both sports potential and comfort. The seat makes it easy for riders to shift their weight during sport or track riding and increases comfort on long rides. Supersport-style footpegs give the rider a direct feel and good controllability when sport riding. An adjustable brake and clutch lever each offer five position settings that allows the rider to set them to suit their hand size and preference.

STYLING

The aggressive Ninja styling of the Ninja ZX-4RR KRT Edition was designed to deliver a fierce look that contains its power and explosive action, benefitting the most powerful machine in the 400cc class. Prominently located at the center of the upper cowl, the Ram Air intake is a trademark feature on Ninja ZX models, setting the machine apart from its competition. It’s stamped with “Ram Air”, leaving a reminder of the bike’s high performance. A sharp chin spoiler further contributes to the strong Ninja family image. The supersport-style low fuel tank and minimalist tight-fitting bodywork that wraps around the in-line four engine gives the Ninja ZX-4RR KRT Edition a compact, high-class look. Sharply angled lines contribute to a lightweight image that reflects the bike’s nimble supersport-style handling. Side air ducts in the fairings provide a blend of form and function, directing cool air into the engine and adding aggressive lines for a stylish design. The upswept angle of the slim, race-style tail cowl puts off a lightweight appearance and the rear flap can easily be removed for track days.

Twin LED headlights help the Ninja ZX-4RR KRT Edition stand out and provide excellent illumination, while LED front turn signals are built into the fairings. The LED taillight was inspired by the Ninja ZX-10R, adding a high-grade touch to the rear of the motorcycle. Both the license plate bulb and rear turn signals are LED, completing the full LED package.

ACCESSORIES

A wide range of Kawasaki Genuine Accessories (KGA) are available and allow riders to personalize their Ninja ZX-4RR KRT Edition motorcycles. This includes a sport seat with firm urethane cushioning that makes it easier to feel the rear wheel traction during sport riding sessions and a USB outlet that provides a convenient charging point and is accessible under the seat. Other accessories such as a pillion seat cover, frame slider, tank pad, radiator screen, and meter protector are also available.

Moto2: American Racing Team Holds Training Camp In Southern California

The American Racing Team’s 2023 lineup of Sean Dylan Kelly and Rory Skinner were reunited in January for the team’s inaugural three-week winter training camp in California. They were joined by the American Racing Academy’s newest member, Max Toth, who is preparing for his first season in the JuniorGP European Moto2 class.

Thanks to key partners of the team, Family Powersports Texas and the W Training Facility, the trio were flat-out for three weeks taking on as many disciplines of motorcycle riding as possible, sharpening their skills with Motocross, Supermoto, Flat Track, Enduro and mini bikes, while taking their fitness to new heights in the gym and on mountain bikes between riding sessions. Along with expert tuition from our Racing Director John Hopkins, the riders were able to pit themselves on track against 2021 MotoGP World Champion Fabio Quatararo and fellow Moto2 competitor Tony Arbolino thanks to Johnny Louch at the W Training Facility.

A vital part of the American Racing Academy program is engaging the next generation of American talent with our European and World-level riders, through sharing the same track, and learning the methods & work ethic put into training regimes from the likes of Sean, Rory and Max. This gives them further insight into the world that they are aspiring to be a part of and to continue chasing for the future.

With the extended MotoGP calendar and the team aspect becoming all the more important with the intense travel schedule, the team opted to rent a house in the Temecula Wine Country area for the riders to stay in with some of the team, getting to know each other better before the 2023 lap of the world begins.

The riders go their separate ways for February before the team heads to the first pre-season tests ready for round one at Portimao in March!

Sean Dylan Kelly, #4 –

The training camp was absolutely amazing! I’ve never done something like this before. It was hugely intense with only two rest days in sixteen total of me being out there. It was action-packed full of different disciplines: from gym, to mountain biking, supermoto… mini dirt bikes… full flat track and motocross, pretty much everything including the Ohvales – very, very intense! I would say that one of the highlights for me was riding with Robbie Maddison at his place in his yard. There was a lot of sick days but that was the stand out to be sharing that time with a legend! It didn’t all quite go to plan though, for example, I wasn’t supposed to ram a tyre wall. That wasn’t intended but a nice false neutral on the supermoto led to my biggest crash in quite a while, fortunately with no consequences! On the plus side, we got it on video, so that’s all that really matters! Was really cool riding with Fabio and Tony. I’ve never spoken to Fabio before but he was really cool and a super chill guy. Tony is one of our competitors and was great to ride on the minibikes with him too.

Was cool to spend time with Rory here as well, starting that teammate relationship with something like this and everyone together. It’s so awesome to have a team like American Racing that puts events like this on, it really gets the most out of us all and looking forward to seeing it pay off on the track this year!

Rory Skinner, #33 –

I had a great time. Every day kind of just merged into one. Flat out from the start with limited rest, sixteen days in total and having just two to really chill out. California is super cool. I’m loving it here. So much so that I’m staying for another three weeks at Hopper’s house to train some more. For me, the highlight in general was riding in the warmth of the Californian winter… you can imagine it’s not the same as home. Was super cool to ride with the Maddison family, Fabio and Tony. Wasn’t just on the bike though, being altogether as a team before and after was a real highlight as well. Was a great trip for us all to get to know each other better before we’re all on the road for so long. The American Racing Team is the best. The camp was amazing.

John Hopkins, Racing Director –

It’s been an awesome, awesome few weeks, even while I’m still recovering from my godsend of a hip replacement! But was great that I still managed to get out with the boys riding motocross on the pro track a week later! We were non-stop for nine-ten days straight on every type of riding: supermoto, minibike, dirt track, enduro… it was awesome, really good for all the riders to get that kind of experience. The aspects of MX and dirt track are hugely relevant in terms of what they’ll do on the road race bike: picking it up, getting it turned, your body positioning and bike control, all of it is extremely relevant to Moto2 – everything helps!

I’m very confident that these last couple of weeks will have brought them all heaps of confidence to be ready to go for the season. At the end of the day, seat and bike time is all about bike fitness. You could train your ass off in other ways, be the fittest guy out there but then get on the bike and find you’re not using those same muscles, so bike fitness is a whole other category. Sean’s headed back to Florida now to spend time with family before heading to Spain for the final stage of pre-season, get himself riding over there – it’s obviously a place he knows well and he speaks the language so that’s right for him. Rory has opted not to go back to Scotland for now and actually staying with me for a little longer. We’ll be putting in some more rides, MX trail riding, supermoto and get him on the Ohvale some more, too. On top of that, they’ve been doing a load of mountain biking, had full access to the W Training Facility with my good friend, Johnny Louch, so it’s been a great trip. Organising something like this was huge and we think it’ll pay off in the long run. We’re already counting down the days till round one!

MV Agusta Exits “Composition With Creditors,” Settles All Debts

MV AGUSTA ANNOUNCES FINAL RESOLUTION OF COMPOSITION WITH CREDITORS

MV Agusta Motor S.p.A. announces the final resolution of the composition with creditors, “Concordato Preventivo in Continuità Aziendale” under Italian law.

The Varese Court, in its ruling of December 29th, 2022, declared the procedure as resolved, after having ascertained that all outstanding debt with creditors and all obligations under the composition had been entirely settled.

The exit from the Composition with Creditors finalises the restructuring process of MV Agusta Motor S.p.A.. An outstanding result that was made possible thanks to the strong commitment of the Sardarov family, who took control of the company 4 years ago and supported it financially since the beginning of the Composition in 2017, by injecting more than 180€ Million in order to restructure all of the business practices, pay off all debt under the procedure, support MV Agusta’s day to day operations and make sure that the company has a solid business plan for the future growth.

The arrival of the new partner, KTM AG, a company of PIERER Mobility AG, proves that MV Agusta was put on the right path and marks a new positive development under the leadership of CEO Timur Sardarov, who is adamant that a difficult phase in the company’s history is officially over, and that now MV Agusta has a solid base to live up to its status of one of the greatest brands in motorcycle history.

Timur Sardarov, CEO of MV Agusta Motor S.p.A., said: “Since my arrival at MV Agusta, the settlement of the Composition with Creditors has been one of my main objectives, in order to regain the trust of our clients and our suppliers. Despite the negative effects of the pandemics, the strong increase in the cost of raw materials and the outbreak of war in Ukraine, the engagement and the professionalism of MV Agusta’s management brought this important result home. We must now look at the future with renewed confidence, comforted by the success of our new models. The partnership with KTM AG is already bringing new energy to our business on all fronts, from the production of new models and the expansion of our dealers network to the improve of the services quality for our clients. Our dark years are over, as we have finally created the conditions for MV Agusta to write a new chapter in the history of motorcycling.”

WorldSBK: Kawasaki Bolsters Electronics Staff With Donkers & Lambert

New Personalities Join The Kawasaki Family

One key to the continuing success of the official Kawasaki Racing Team in WorldSBK is the stability and ‘family feel’ of the entire set-up, both at races and back at headquarters in Europe and Japan. This year two new staff have joined the KRT team itself, in the shape of Electronics Engineer for Jonathan Rea, Sander Donkers, and an experienced WorldSBK figure in the electronics realm, Christophe Lambert.

The whole Kawasaki Racing family has expanded with the appointment of the two new electronics and data analysis specialists. The word ‘family’ can be sometimes overused in a sporting context but not only is the unmistakable feel inside Kawasaki’s official squad akin to a family unit, the Provec Racing element of the overall KRT effort is actually run by two bothers – Guim and Biel Roda – and their cousin, Alvar Garriga.

It was identified recently that there had to be changes in the way that the team could process and act upon conclusions derived from the vast reams of data that are gathered from test sessions and races. Hence the arrival of Lambert and his vast experience of electronics in WorldSBK, most recently with Yamaha. His official title will be Electronics and Data Engineering Coordinator. As this new job title suggests, Christophe’s arrival signals an overall expansion of the team’s efforts in terms of electronics, with the sole aim of improving on-track performance when it really matters, during race weekends.

Sander Donkers is a direct replacement for Rea’s previous electronics engineer Davide Gentile, a respected colleague and friend who leaves for another challenge with best wishes from all in Kawasaki after his positive contribution to much of the team’s recent successes.

With two new engineering specialists in place, Sander and Christophe, the whole team will pull together to identify issues, improve working collective practices and aim for wins, all while representing the best of Kawasaki’s competitive spirit and desire to succeed. This ambition for even more success is shared by the Kawasaki fans, riders, sponsors, technical partners, KRT itself and everyone involved in the whole global Kawasaki family.

By his own admission Christophe came into the exciting world of bike racing quite late, at the age of 25. The bike trackday enthusiast was bored in his regular job designing car air-conditioning systems, when a friend encouraged him to try to get a job inside MotoGP. He started studying at the French ‘l’Ecole de La Performance’ (Motorsports performance school) to immerse himself in the racing world and build up relationships with existing racing professionals. He entered his on-track career as the ‘data guy’ in a French 250cc MotoGP team. Moving to WorldSBK and working in smaller teams at the beginning, he has made his way right up to factory level. He has even worked with now regular KRT rider Alex Lowes when he was at Yamaha, and for the past three years he has worked with 2021 WorldSBK champion, Toprak Razgatlioglu.

Sander has an impressive breadth of experience in many forms of racing and different championships. Entering the HAN University in his native Netherlands in 1999, he secured a BEng Automotive Engineering and then went straight to the specialist Cranfield Institute to earn a Masters Degree in Motorsport Engineering & Management. Although now specialising in electronics, he was hand-and-mind working experience as a suspension designer in the UK, an electronics engineer in AMA Superbike racing, a crew chief, a Moto2 R&D Engineer, a MotoGP electronics engineer, and various electronic engineering roles for MV Agusta, HRC and most recently BMW in WorldSBK.

After many achievements in their respective careers, Christophe and Sander are now part of the most successful WorldSBK effort in the past decade, looking to work alongside many of their new colleagues who have been part of that success in their past, and who are equally hungry for more in the very near future.

The new KRT technical figures are far from hidden, having already joined with their perennially committed and hard working colleagues in a test at Jerez in Spain, and will continue to build their working and personal relationships at the next test, in Portimao, between 31 January and 1 February.

Christophe Lambert, stated: “I am really happy to join KRT. It has been something that has stimulated me over the past years. They have been at the top for a long time. It’s super-exciting for me to join them. The resources are amazing and the people are very friendly, and very professional. I think it will be a very nice experience for me.”

Sander Donkers, stated: “I will be joining KRT from 2023 on, as an electronics guy for Johnny. I am really excited to join this project. It will be a big challenge for me, with a lot of new things to learn, but I am really excited to get started.”

Guim Roda, KRT Team Manager, stated: “After analysing areas in KRT workflow that we could enhance we detected the need to introduce a new role to support the technical staff more and to extract the maximum from the electronics system. At the same time, we need to evaluate the quantity of data we generate on race weekend much faster. In the past, we have realised where we could have been better a few days after the race – which is inefficient. This new staff situation allows us to better analyse all the information we create to react fast in real time during the race weekend. We found in Christophe good experience and potential and we are quite sure we gonna make another step to improve our performance with him onboard. Additionally, Davide Gentile the Electronics Engineer for Jonathan has decided to look for new goals and we wish him well and thank him for his contribution to the project. For this important role we searched in many places and finally we decided on Sander as the best candidate to work with Pere and Johnny. Additionally, we have taken the opportunity to reorganise some roles and responsibilities within KRT, adjusting concept ideas to the reality of racing and we will reinforce the Test Team area with Florian Marino helping us to use best our track time. We are all highly motivated for 2023 season and for sure we’ll do our best to keep improving, keep innovating and never give up.”

Kawasaki Launches All-New 16,000 RPM Inline-Four Ninja ZX-4RR

This circuit-focused motorcycle combines real-world road enjoyment and track riding potential and provides the rider the satisfaction of being able to ride with confidence. The Ninja ZX-4RR KRT Edition is designed for the rider seeking a new exhilarating riding experience.

The Ninja ZX-4RR KRT Edition features a new, powerful 399cc in-line four-cylinder engine that produces music to the ears with its high-performance audible signal – helping it stand out from the competition. Thanks to its lightweight trellis frame, it is compact and nimble for exciting cornering performance. Dual front disc brakes and a high-performance Showa SFF-BP front fork as well as BFRC Lite rear shock have been fitted to ensure that the Ninja ZX-4RR KRT Edition breeds performance from the ground up.

The long list of impressive features doesn’t stop there as the Ninja ZX-4RR KRT Edition boasts numerous premium features that include a 4.3” TFT color instrumentation with smartphone connectivity, integrated riding modes that link Kawasaki TRaction Control (KTRC) and Power Modes, dual-direction Kawasaki Quick Shifter (KQS), and aggressive Ninja® ZX™ family styling that make it clear this is a high-performance supersport model from Kawasaki.

2023 NINJA ZX-4RR KRT EDITION HIGHLIGHTS:

NEW All-new 399cc liquid-cooled, 4-stroke, in-line four cylinder engine
NEW World Superbike-inspired chassis design
NEW Dual front disc brakes
NEW High-performance suspension
NEW Ergonomics for control and comfort
NEW Fierce Ninja ZX styling

ENGINE

The Ninja ZX-4RR KRT Edition boasts an all-new 399cc liquid-cooled, 4-stroke, in-line four cylinder engine that delivers exhilarating performance and fun-to-ride power. Developed with feedback from other Kawasaki Ninja ZX supersport machines, the all-new engine found on the Ninja ZX-4RR KRT Edition features a quick-revving nature with a direct throttle response that combines strong low-mid range torque for city riding and high-rpm power that can be enjoyed when riding on the track. As riders roll on the throttle, they are rewarded with a satisfying surge of acceleration that is complemented by the distinct intake and exhaust notes of a Kawasaki in-line four cylinder engine.

The liquid-cooled, DOHC, 16-valve, 399cc in-line four cylinder engine features a bore and stroke of 57.0 x 39.16mm and packs impressive power and strong torque. The bore and stroke contributes to the impressive top-end power. A high-spec ECU is similar to that found on the Kawasaki Z H2, which allows for the use of Kawasaki’s latest electronics. Electronic Throttle Valves (ETV) with 34mm throttle bodies provide smooth, natural engine response by enabling the ECU to control the volume of both the fuel (via the injectors) and the air (via throttle valves) delivered to the engine. Additionally, they facilitate the use of Kawasaki electronic rider support systems such as integrated riding modes with traction control, selectable power modes, and a dual-direction Kawasaki Quick Shifter (KQS) that allows riders to feel “at one” with their machine.

Intake port interiors are sand cast using fine sand, which results in a smooth finish. Similar to the Ninja® ZX™-10R, the intake port exits have been machined in two stages, first along with the valve seats and then again at an inclined angle, to create a straighter path for intake air as it enters the combustion chamber. The straighter and wider path for the intake air promotes a smoother flow and a greater volume of fuel-air mixture that contributes to the engine’s high performance. Lightweight forged camshafts contribute to the high-revving and high-rpm performance.

Large 22.1mm intake valves are complemented by 19mm exhaust valves, flowing a great volume of air for excellent high-rpm performance. Triple-rate valve springs accommodate the valves and add to the Ninja ZX-4RR KRT Edition’s high-rpm performance. A narrow valve angle helps combustion efficiency as well as achieves a compact engine design. The combustion chambers are precision machined to high tolerances – a production technique that is limited to Kawasaki’s high-performance premium models.

Lightweight cast aluminum pistons contribute to low reciprocating weight for quick-climbing revs. The piston skirts have a molybdenum coating that increases durability. The piston crowns were designed to develop compression, which contributes to the 12.3:1 compression ratio that is found on the Ninja ZX-4RR KRT Edition and optimized to allow the use of regular gasoline while achieving strong performance. The piston’s wide bore facilitates the use of the large intake and exhaust valves for greater air flow, while their short stroke adds to the high-rpm performance. Utilizing an aluminum die-cast cylinder with an open-deck design, excellent heat dissipation and low engine weight is achieved.

In order to reduce mechanical loss and vibration, Kawasaki engineers carefully selected the connecting rod ratio, while a special carburizing treatment was used on the connecting rods to improve durability and reduce weight. Thanks to the crankshaft’s light flywheel mass, a low moment of inertia was reached, contributing to a quick-revving engine character and direct throttle response. A deep oil pan ensures that the oil pump inlet is always submerged, blocking air from being ingested, even during hard acceleration and deceleration while sport or track riding.

ADVANCED ENGINE COOLING

With the Ninja ZX-4RR KRT Edition engine designed for high performance, Kawasaki engineers placed a great emphasis on the engine’s cooling system in order to achieve optimum performance. The water jackets on the cylinder head were carefully designed and long-reach spark plugs offer greater contact with the water jacket, helping to prevent engine knocking. A large, 30-row radiator provides efficient engine cooling to handle the Ninja ZX-4RR KRT Edition’s performance capabilities. Side air ducts are built into the fairings to direct cool air towards the engine and promote heat dissipation that greatly contributes to engine performance. Innovative Kawasaki technology like the patented radiator fan cover that is located behind the radiator directs hot air out to the sides and away from the rider, improving rider comfort. The heat management system was designed using CFD analysis and controls the flow of air, helping keep the tank, frame, and other parts that contact the rider cooler, further increasing rider comfort.

RAM AIR DUCT INTAKE SYSTEM

The Ram Air duct system is a trademark feature on Kawasaki’s Ninja ZX models. It’s a centrally positioned intake that improves filling efficiency and increases engine performance. Following a layout that is similar to that of the Ninja H2, the Ram Air duct is routed to the left of the front fork on its way to the airbox. This contributes to a duct with a highly efficient airflow, enabling cool, high-pressure air from the front of the bike to be ingested. Engine performance is increased at all rpm thanks to the increased pressure and cooler air. Additionally, the design is extremely effective at preventing water from entering the airbox while riding in the rain. The large Ram Air duct has “Ram Air” stamped into it, which is visible to the rider and adds to the Ninja ZX-4RR KRT Edition’s high-performance look and feel. Intake funnels, consisting of 60mm and 40mm lengths, contribute to efficient filling and produce a flat torque curve with smooth power delivery. The downdraft intake creates a shorter, more direct path for intake air to enter the cylinder, improving cylinder-filling efficiency and increasing engine power, especially at high rpm.

EXHAUST

The header pipes and collector pipe layout were built with inspiration from the Ninja® ZX™-6R. Joint pipes link the headers, contributing to a strong power output while meeting emissions and sound regulations. A traditionally styled, long silencer produces a clear, racy exhaust note that is distinct to that found on a Kawasaki in-line four cylinder engine. The collector pipe features triple catalyzers to ensure emissions are met and their position makes it easy to add a slip-on muffler.

TRANSMISSION & CLUTCH

Complementing the high-performance 399cc engine is a smooth-shifting six-speed transmission that is designed to shine in all riding situations. It’s especially well suited for riders accelerating out of corners when sport or track riding and features a dual-direction Kawasaki Quick Shifter (KQS). Developed through Kawasaki’s racing efforts, the Ninja ZX-4RR KRT Edition is fitted with an Assist & Slipper Clutch that uses two types of cams (an assist cam and slipper cam), offering two functions that are not available on a standard clutch. When the engine is operating at normal rpm the assist cam functions act as a self-serve mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, resulting in a lighter clutch lever pull when operating the clutch. When excessive engine braking occurs, the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back torque and help prevent the rear tire from hopping or skidding.

ELECTRONICS

KAWASAKI TRACTION CONTROL (KTRC)

Kawasaki’s advanced KTRC system provides both enhanced sport riding performance and peace of mind under certain conditions to negotiate low-traction surfaces with confidence. Three selectable modes offer progressively greater levels of intrusion that cut fuel and ignition to help maintain traction and forward drive as well as suit the riding situation and rider preference. The system uses a number of parameters to get an accurate real-time picture and adapt accordingly. Mode 1 is the least intrusive and designed with sport riding in mind, Mode 2 intervention occurs earlier offering a balance of sport riding support and rider confidence, and Mode 3 is the most intrusive for navigating low-traction conditions. In addition to the three modes, the rider can elect to turn the system OFF.

POWER MODES

Power Modes offer riders an easily selectable choice of engine power delivery to suit riding conditions or preferences. In addition to Full Power mode, one (Low) alternate mode in which maximum power is limited and throttle response is milder is provided.

INTEGRATED RIDING MODES

All-inclusive modes that link KTRC and Power Mode allow riders to easily set traction control and power delivery to suit a given riding situation. Riders can choose from three settings (Sport, Road, Rain) or a manual setting (Rider). In the manual Rider mode, each of the systems can be set independently.

KAWASAKI QUICK SHIFTER (KQS)

Adding to its impressive list of high-performance features, the Ninja ZX-4RR KRT Edition comes equipped with dual-direction KQS. The KQS allows ultra-quick upshifts and downshifts without the need to use the clutch, resulting in a more enjoyable experience and quicker lap times. Designed for more effective sport riding, KQS can also be used on the street when the engine is above 2,500 rpm.

TFT COLOR INSTRUMENTATION

The 4.3” all-digital TFT color instrumentation gives the cockpit a high-tech, high-grade appearance and features a Circuit Mode that allows lap timing and shows track-related information in a more prominent and easier-to-view layout. The high-grade color LCD screen features TFT (thin-film transitory) technology, delivering a high level of visibility. Selectable background and text colors can be chosen to suit light or dark conditions and screen brightness automatically switches between five levels to suit available light.

Display functions include a digital speedometer, digital bar-style tachometer, gear position indicator, shift indicator (tachometer flashes), fuel gauge, odometer, dual trip meters, current and average fuel consumption, remaining range, average speed, riding time, coolant temperature, clock, battery voltage, lap timer (Circuit Mode only), Kawasaki service reminder, oil change reminder, integrated riding mode, KTRC and power mode indicators, smartphone call and mail notices, Bluetooth indicator, economical riding indicator, and KQS indicator.

Circuit mode can be toggled for use at track days and changes the display to make information for track riding more visible. This includes showing the lap time in the center with large text so that it can easily be ready while riding. The gear position and tachometer display is also more visible along the top when above 10,000 rpm, giving riders a clear view of the information needed when working towards faster lap times on the track.

RIDEOLOGY THE APP

Bluetooth® technology built into the instrument panel enables riders to connect to their motorcycle wirelessly. Using RIDEOLOGY THE APP*, a number of instrument functions can be accessed, logged, and reviewed contributing to an enhanced motorcycling experience. The following information can be viewed:

CHASSIS

The Ninja ZX-4RR KRT Edition delivers light maneuverability when riding around town, however, its high-level supersport character shines when out sport riding on backroads or at the racetrack. Utilizing feedback derived directly from Kawasaki Racing Team’s (KRT) efforts in the FIM World Superbike Championship, Kawasaki engineers carefully selected key chassis components to achieve excellent rigidity balance. Formed from high-tensile steel, the trellis frame features various pipe diameter thicknesses with a swingarm pivot section. Kawasaki’s advanced dynamic rigidity analysis was used to ensure the required balance of strength and chassis flex.

Key chassis dimensions, such as center of gravity position, swingarm pivot position, engine axis positions, and the caster angle were inspired by Kawasaki’s World Superbike Ninja® ZX™-10RR, bringing World Superbike chassis design to the 400cc class. The long-style swingarm is made from high-tensile steel and allows the bike’s front-rear weight distribution to be set for the perfect balance of nimble handling and composed chassis behavior. An arch design on the right side of the swingarm delivers the required balance of rigidity and flex, enabling the silencer to be positioned as centrally as possible while adding to the Ninja ZX-4RR KRT Edition’s stylish, sporty looks.

SUSPENSION

To complement the optimal rigidity balance of the chassis, the Ninja ZX-4RR KRT Edition front end is held up by a 37mm inverted front fork that features Showa’s SFF-BP (Separate Function Fork – Big Piston) technology. This advanced fork offers both racetrack performance and everyday usability. The technology is similar to that on the Ninja ZX-6R, while the spring rate and damping characteristics were developed specifically for the Ninja ZX-4RR KRT Edition. The front fork provides smooth action at the initial part of the stroke that contributes to excellent composure under braking. A large-diameter damping piston is used in the SFF-BP fork, which is much larger than that used in a cartridge-type fork. This allows oil inside the fork to act on a much larger surface area and damping pressure to be reduced while ensuring the same damping force. By reducing the damping pressure, it allows the slide pipe to move more smoothly, which is especially noticeable during the initial part of the stroke. This design allows for greater control as the fork begins to compress and a smooth transition as the Ninja ZX-4RR KRT Edition’s weight shifts forward when reducing speed, offering greater chassis stability on corner entry and a planted feel when braking. The fork settings were designed to accommodate a wide range of riding situations, from the city to the racetrack. The spring preload is adjustable and can be tailored to suit the rider’s preference, which is the first use of adjustable SFF-BP in the 400cc class.

At the rear of the Ninja ZX-4RR KRT Edition, horizontal back-link rear suspension mounted to a Showa BFRC (Balance Free Rear Cushion) Lite shock can be found. The shock is similar to that found on the Ninja ZX-10R and has been specially tuned for the Ninja ZX-4RR KRT Edition. Its excellent movement at the start of the stroke ensures comfort in day-to-day riding as well as a planted feel when riding on the track, while linear damping characteristics provide a stable, solid feel and peace of mind for the rider in a wide variety of situations. Additionally, it offers adjustable compression and rebound damping as well as adjustable spring preload so that riders can fine-tune the rear end to suit their riding preferences. The horizontal back-link rear suspension positions the shock unit and linkage above the swingarm and out of the way from engine and exhaust heat. A firm rear shock feel achieves a planted feel that is reassuring during sport riding, while also offering ample absorption for ride comfort when riding around town.

WHEELS & BRAKES

In order to stop the powerful Ninja ZX-4RR KRT Edition, a pair of 290mm semi-floating front discs handle the stopping duties up front and are gripped by 4-piston radial-mount monobloc calipers. The calipers feature different diameter pistons with the upper piston measuring 32mm and the lower piston 30mm. Dual front discs were chosen for additional stopping power and the monobloc calipers help achieve a firm initial touch. Brake pad selection contributes to both brake force and braking controllability.

At the rear, a 220mm disc is slowed by a single-piston caliper that is powered by a 38mm piston. The master cylinder, caliper, brake pedal, and brake pad material were carefully selected for a balance of stopping power and control. Equipped with ABS, the Ninja ZX-4RR KRT Edition features Nissin’s latest ABS control unit that has been specially developed to deliver precise control and is the most compact and lightweight unit available.

Stylish star-pattern five-spoke wheels contribute to the bike’s overall lightweight and their high rigidity improves handling. The wheels also contribute to the bike’s light, nimble appearance. Dunlop Sportmax® GPR-300 radial tires are mounted on the front and rear, offering high grip in both wet and dry conditions and contributing to agile handling and excellent riding comfort. A 120/70ZR17 tire is used on the front and 160/60ZR17 is fitted on the rear.

ERGONOMICS

To take full advantage of the Ninja ZX-4RR KRT Edition’s nimble, supersport-style handling is a naturally aggressive riding position that is more forward-leaning than that found on the Ninja 400. The riding position on the Ninja ZX-4RR KRT Edition offers a good balance of wind protection and aerodynamics that enable the rider to tuck in to get out of the wind, while still maintaining a relaxed feel. A slim design of the fuel tank between the rider’s legs promotes good contact with the bike and a low design on the top of the fuel tank facilitates the rider getting into a tucked position. A firm seat cushion offers both sports potential and comfort. The seat makes it easy for riders to shift their weight during sport or track riding and increases comfort on long rides. Supersport-style footpegs give the rider a direct feel and good controllability when sport riding. An adjustable brake and clutch lever each offer five position settings that allows the rider to set them to suit their hand size and preference.

STYLING

The aggressive Ninja styling of the Ninja ZX-4RR KRT Edition was designed to deliver a fierce look that contains its power and explosive action, benefitting the most powerful machine in the 400cc class. Prominently located at the center of the upper cowl, the Ram Air intake is a trademark feature on Ninja ZX models, setting the machine apart from its competition. It’s stamped with “Ram Air”, leaving a reminder of the bike’s high performance. A sharp chin spoiler further contributes to the strong Ninja family image. The supersport-style low fuel tank and minimalist tight-fitting bodywork that wraps around the in-line four engine gives the Ninja ZX-4RR KRT Edition a compact, high-class look. Sharply angled lines contribute to a lightweight image that reflects the bike’s nimble supersport-style handling. Side air ducts in the fairings provide a blend of form and function, directing cool air into the engine and adding aggressive lines for a stylish design. The upswept angle of the slim, race-style tail cowl puts off a lightweight appearance and the rear flap can easily be removed for track days.

Twin LED headlights help the Ninja ZX-4RR KRT Edition stand out and provide excellent illumination, while LED front turn signals are built into the fairings. The LED taillight was inspired by the Ninja ZX-10R, adding a high-grade touch to the rear of the motorcycle. Both the license plate bulb and rear turn signals are LED, completing the full LED package.

ACCESSORIES

A wide range of Kawasaki Genuine Accessories (KGA) are available and allow riders to personalize their Ninja ZX-4RR KRT Edition motorcycles. This includes a sport seat with firm urethane cushioning that makes it easier to feel the rear wheel traction during sport riding sessions and a USB outlet that provides a convenient charging point and is accessible under the seat. Other accessories such as a pillion seat cover, frame slider, tank pad, radiator screen, and meter protector are also available.
