      The story of this bike’s 1983 race season is a road
race version of David and Goliath.

      When the AMA reduced nominal engine size from
1025cc to 750cc for the increasingly popular Superbike class, it sent shock
waves through the racing community. All the knowledge and painstaking work from
previous years was negated by the stroke of the rule maker’s pen.

      The claimed rationale was to attract more
factory-backed teams; however, Suzuki and Yamaha watched from the sidelines,
leaving only Honda and Kawasaki participating with factory bikes. Honda was
more than ready with the VF750R (See the July 2018 issue of Roadracing World,

But Kawasaki’s U.S. race team did not get deliveries of the new GPz750 until
the start of the 1983 season.

      Compared to Honda’s water-cooled, 4-valve V4 VF750R
racebike, the GPz was at best old-school, almost vintage! The transverse Inline
Four air-cooled engine with two valves per cylinder sat in a conventional
twin-loop, steel-tube frame.

      Predictably, Kawasaki factory riders Wes Cooley and
Wayne Rainey had a tough season opener at Daytona. Reliability issues dogged
the pair in practice and were responsible for Cooley retiring in the race. The
best Rainey could do was a distant fourth. As if Honda’s technical advantage
was not enough, the grids were packed with race-kitted VF750R’s fielded by
dealers …

Kawasaki
didn’t let a tough start to the 1983 season keep it down for long. The factory team
dug in and developed the venerable GPz into a racebike that, in the hands of Wayne
Rainey, was good enough to take the AMA Superbike Championship. The details of the
development are in the August 2019 issue of Roadracing World!

MotoAmerica: Championships On The Line This Coming Weekend At New Jersey Motorsports Park

It’s Nearing Title Time In MotoAmerica Series

Championships On The Line Heading To NJMP

COSTA MESA, CA (September 5, 2019)– While two riders are on the verge of capturing titles in the 2019 MotoAmerica Series, the other three classes are still wide open with gaps ranging from 11 to 35 points – including the premier EBC Brakes Superbike Championship – as the series heads to New Jersey Motorsports Park this weekend for the MotoAmerica Championship of New Jersey.

With his 75-point lead in the Liqui Moly Junior Cup Series, 14-year-old Rocco Landers is the rider facing the least resistance en route to the title and barring catastrophe he will wrap up the championship on Saturday in race one. With his nearest competitor, Dallas Daniels, not scheduled to take part in the last two rounds, Landers leads third-placed Kevin Olmedo by 77 points with 100 points (four races) up for grabs. Thus, if Landers wins on Saturday and Olmedo finishes second, the Ninja400.com/Norton Motorsports/Dr. Farr-backed rider from Oregon will lead by an insurmountable 82 points going into Sunday’s race two.

Landers has won 10 races thus far in 2019 with Daniels (1 win), Olmedo (1 win) and Cameron Jones (1 win) the only others to win races in the class.

The Stock 1000 Championship, meanwhile, is also well within the grasp of Andrew Lee and his Franklin Armory/Graves Kawasaki team. Lee holds down a 48-point lead over Stefano Mesa with three races remaining for that class. The Stock 1000 class will race once this weekend at NJMP and twice in the series finale at Barber Motorsports Park, September 20-22. If Lee wins on Sunday afternoon and Mesa finishes second, Lee will leave New Jersey with a 53-point lead with just 50 points left on the table at Barber.

Lee, the defending Stock 1000 Champion, has won four races in a row and five out of the eight races held prior to NJMP.

The other three classes are still unresolved with the champions likely not crowned until the final race concludes at Barber.

The Twins Cup only has two races left on its 2019 schedule – Sunday’s race at NJMP and the lone race in the finale at Barber. Roadracing World Young Guns’ Alex Dumas has a nine-point lead over The Draik 77’s Draik Beauchamp heading into New Jersey with Michael Barnes and his Quarterley Racing Ducati another 10 points behind in third. And the list of potential spoilers is long and includes defending class champion Chris Parrish and his Ghetto Customs Suzuki who can no longer defend his title but will be hungry to make his mark in the final two races.

Dumas holds the hot hand in the class with three wins in a row and four total for the 2018 Liqui Moly Junior Cup Champion, who has made the jump to the Twins Cup class a successful one.

With four races left on the Supersport schedule, just 20 points separate the top three as the series heads to NJMP. M4 ECSTAR Suzuki’s Bobby Fong leads the way with an 11-point lead over Rickdiculous Racing’s Hayden Gillim, 220-209. Celtic HSBK Racing’s PJ Jacobsen is third, 20 points behind Fong and nine behind Gillim. Fong’s teammate Sean Dylan Kelly, the class rookie who won both races at the last round in Pittsburgh, lurks in fourth place – 45 points out of first.

With his two wins at PittRace, Kelly became the fourth different winner in the class – joining Fong (4 wins), Gillim (5 wins) and Jacobsen (2 wins).

That brings us to the EBC Brakes Superbike class where Yoshimura Suzuki’s Toni Elias leads Monster Energy/Yamalube/Yamaha Factory Racing’s Cameron Beaubier by 35 points with four races (100 points) left to run. Elias has put together a seven-win season with Beaubier winning three races so far. Beaubier’s teammate Garrett Gerloff, meanwhile, has also won three races, but his DNF in race two at PittRace two weeks ago put a damper on his championship aspirations as he now trails Elias by 56 points.

Attack Performance Estenson Racing’s JD Beach, who has won once in 2019, sits fourth in the title chase, just six points better than two-time winner Josh Herrin on the second Yoshimura Suzuki. Herrin, in turn, is just 12 points clear of Westby Racing’s Mathew Scholtz as the battle for fourth in the championship likely won’t be decided until the final race.

M4 ECSTAR Suzuki’s Jake Lewis is coming off his best result of the season at PittRace, the Kentuckian leading several laps early on before ending up fourth in race two. Lewis is currently seventh in the championship, 22 points behind Scholtz and 34 points ahead of eighth-placed Jake Gagne on the Scheibe Racing BMW.

Omega Moto’s Cameron Petersen is just a single point behind Gagne in ninth and 13 points ahead of FLY Racing ADR Motorsports’ David Anthony, the Australian rounding out the top 10 heading to New Jersey.

NJMP Fast Facts…

With his race-two win at PittRace two weeks ago, Toni Elias now has 32 AMA Superbike wins on his resume. And that mark matches the MotoAmerica Superbike win total of 32 for Cameron Beaubier. Beaubier, however, won three AMA Superbike races before MotoAmerica took over the series and that gives him 35 total victories in the class.

Those 35 wins puts Beaubier third on the all-time AMA Superbike win list behind Mat Mladin (82) and Josh Hayes (61). Elias, meanwhile, is now tied with Miguel Duhamel for fourth with his 32 wins. Ben Spies, Fred Merkel, Nicky Hayden, Wayne Rainey and Eric Bostrom round out the top 10 on the all-time win list.

Elias has an opportunity to equal or surpass his championship-winning, 10-race-win season of 2017 with victories in the four races left in the 2019 MotoAmerica Series. Elias has seven wins going into NJMP and winning out would give him 11 victories on the year.

With his 10th win of the season coming in race one at PittRace, 14-year-old Rocco Landers equaled the win total set last year by 2018 Liqui Moly Junior Cup Champion Alex Dumas. The rider with the next highest total of wins in the class is Ashton Yates with three wins. Dumas, meanwhile, with his four Twins Cup wins this season, has moved ahead of 2018 Twins Cup Champion Chris Parrish as the win leader in that class.

Westby Racing’s Mathew Scholtz earned pole position for last year’s Superbike races at NJMP with his 1:38.154 set during the Superpole session. As is the norm for MotoAmerica’s two-day events, Superpole won’t be held this year at NJMP. The grid will be set based on lap times from the two qualifying sessions on Saturday.

Superbike race one a year ago was won by Josh Herrin over Scholtz and Beaubier in dominating fashion in precarious conditions. Herrin, who is now on the Yoshimura Suzuki team, rode the Attack Performance/Herrin Compound Yamaha YZF-R1 to a 37-second victory over Scholtz. Cameron Beaubier emerged victorious in an extremely wet race two, besting Roger Hayden by 13.6 seconds with Toni Elias finishing third. The victory, his eighth of the year, wrapped up a third championship for Beaubier.

Hayden Gillim and JD Beach split Supersport wins at NJMP a season ago, with Beach’s runner-up finish in race one enough to earn him his second MotoAmerica Supersport Championship. Beach is now in the EBC Brakes Superbike Championship and Gillim is only 11 points behind Bobby Fong in the 2019 Supersport title chase.

El Salvador’s Kevin Olmedo won the first Liqui Moly Junior Cup race of his career a year ago at NJMP in race one; Alex Dumas ended up on top in race two and that earned him the class championship.

Tawfik Khalil was a surprising winner in the Stock 1000 race last year at NJMP; and Kris Turner won the Twins Cup race after beating Brian McGlade by just .003 of a second.

World Superbike: Autodromo Internacional Do Algarve To Host 400th WorldSBK Round

WorldSBK set to celebrate 400th round in Portugal

A landmark achievement for the WorldSBK championship this weekend, as Portimao will be the 400th round in the history of the championship

The MOTUL FIM Superbike World Championship heads to the Autodromo Internacional do Algarve in Portugal for the Acerbis Portuguese Round this weekend for what is already, a historic weekend in the history of the championship. This weekend will mark the 400th WorldSBK round since the championship began back in 1988 at the famous Donington Park circuit. And since that first round took place, we have seen incredible action…

Famous names such as Davide Tardozzi, Marco Lucchinelli, Bubba Shobert and Joey Dunlop lined up on the grid for the first ever round of World Superbike, with an array of machinery and nationalities forming a truly international grid. Today, that legacy lives on, with 10 different countries from three continents competing against each other, across five different factory manufacturers.

Since 1988, there have been some iconic championship-defining moments. At the 100th round, Pierfrancesco Chili won at home at Monza in 1996, after a dramatic final lap. At the 250th WorldSBK event, it was Carlos Checa’s turn to rise to the occasion at the all-new Miller Motorsport Park in Utah in 2008, taking not just his first win but a double.

To add to the occasion of the 400th WorldSBK round, it will be Portimao’s 11th occasion hosting the world’s fastest production-based championship, with a recent contract extension seeing the popular Portuguese venue on the calendar until 2022. This extension secures Portimao in continuing to showcase exciting and memorable moments in WorldSBK, like it has done before.

In 2008, Troy Bayliss completed cleaned up with what would be his last poles, wins and fastest laps in WorldSBK, and what was at the time, his swansong round. In 2009, Ben Spies took a dramatic championship win from Noriyuki Haga, snatching it from the Japanese rider in Race 1 and confirming his title success in Race 2. It was also the first WorldSBK round for Jonathan Rea, who enters his 135th round this weekend.

This year, the WorldSBK title fight is still on, with Alvaro Bautista (ARUBA.IT Racing – Ducati) looking to overcome Jonathan Rea (Kawasaki Racing Team WorldSBK) on his first time at Portimao. In WorldSSP, the BARDAHL Evan Bros. WorldSSP Team duo of Randy Krummenacher and Federico Caricasulo continue to fight, whilst the championship could be decided in WorldSSP300.

Moto2 World Championship: PETRONAS Sprinta Racing Signs Xavi Vierge For 2020

Xavi Vierge joins expanded PETRONAS Sprinta Racing for 2020

Spanish rider will make the move to enlarged PETRONAS Sprinta Racing squad for 2020 Moto2 World Championship

05 September 2019

Three-time Moto2 podium finisher and former European Moto2 championship runner-up Xavi Vierge will join a two-rider PETRONAS Sprinta Racing line-up for 2020, in the squad’s third year of contesting the Moto2 World Championship.

Vierge, 22, from Barcelona, Spain, was most recently on the podium in Argentina and Australia last season where he finished second and third respectively. Next year will be his fifth full season of Moto2 on the international stage.

The 2020 Moto2 season will get underway in March next year, with the opening round at the Qatar Grand Prix provisionally scheduled for 8th March.

Razlan Razali – Team Principal

“For PETRONAS Sprinta Racing the signing of Xavi Vierge is an exciting development. Firstly, he is a quick and well-proven rider who is capable of regular podium performances. Secondly, he will be one of two riders for us in Moto2 as we expand our squad. PETRONAS Sepang Racing Team will have two riders each in Moto3, Moto2 and MotoGP next year. We know it’s been a tough Moto2 season for us in 2019 and we’re hoping that Khairul Idham Pawi will be fully recovered and racing alongside Xavi next season.”

Johan Stigefelt – Team Director

“We’ve brought Xavi into the team as we know he’s a fast rider and we believe he will be able to help us achieve better results in Moto2. Xavi has a lot of experience, and we think he will flourish within our set-up. He’s the right rider to help us grow together in this category and will be the perfect team leader for our two-bike squad next year. This year has been a difficult season for us in Moto2, but with two bikes and a rider of Xavi’s calibre on one of them, we’re expecting better things from 2020.”

Xavi Vierge

“I’m really happy and I can’t wait to get started with the project. PETRONAS Sprinta Racing are amazing; they’re already fighting for wins in Moto3 and MotoGP and I hope I can add Moto2 to that list next year. The potential is really high, I know a lot of the crew, and I feel like they already believe that we can win together. I’m very thankful for everyone who helped make this opportunity happen and I can’t wait to get started. The first target will be to complete really strong winter tests so we can start in Qatar ready to compete for the top positions. The team have the right attitude and I know we can do well.”

Quick Look: Yamaha Tracer 900 GT, A Great Sport-Tourer

Featured In the August 2019 Issue of Roadracing World:

      It’s been a few years since Yamaha decided to unify
model names worldwide, relabeling what were the U.S.-market models with
European market names.

      After doing that, the company refined what was the
FJ-09 in the U.S. and re-named it the Tracer 900, and added an upgraded Tracer
900 GT. The result is a convenient sport tourer capable of covering a lot of
miles in comfort.

      The Tracer 900 and Tracer 900 GT share the FJ-09’s
original liquid-cooled, fuel-injected, DOHC, inline three-cylinder engine, with
a displacement of 847cc coming from a bore and stroke of 78.0mm x 59.1mm.

      Compression ratio is unchanged at 11.5:1, and the
engine continues to feature cylinders offset from the crankshaft to reduce
friction on the power stroke, fracture-split connecting rods, velocity stacks
with staggered lengths, and a “crossplane concept” crankshaft with uneven power
pulses to deliver more linear torque …

Yamaha’s
magnificent inline three-cylinder engine powers a lot of the company’s
vehicles, and the Tracer models put that engine prowess to use in a wide
variety of roles. It’s a tourer that can sport quite nicely, thank you very
much. Read all about Yamaha’s versatile, functional and rapid do-it-all Tracer

AFM: Andrew Lee Takes Another Formula Pacific Race Victory, At Sonoma Raceway

The AFM was back in action Labor Day long weekend at its spiritual home, Sonoma Raceway, for Round Five of the AFM Championship.

Jayson Uribe rushed back from a gruesome injury last round at Thunderhill to keep his AFM number one plate hopes alive. Current AFM number one, Andrew Lee, fresh off his MotoAmerica win at Sonoma just two weeks ago, put up two wins and a strong second-place finish to ensure the title fight continues back to Thunderhill. Lee’s Graves Motorsports teammate, Frenchman Valentin Debise also impressed, securing a hat-trick of wins at Sonoma.

After four rounds split between Thunderhill and Buttonwillow, the AFM rolled into Sonoma for its only stop at the famed race track. Every year Sonoma is an exceptional round for the AFM. The track on Sears Point is a place where many riders make their debut, and many more veterans dust off the leathers for a comeback. This year the throwback feel was stronger than ever, with the AFM teaming up with CSRA to bring Vintage Superbike racing back to the Bay Area. The grids were stacked and great times were had by all, both young and not so young.

The weekend’s racing kicked off with the marquee CSRA Vintage Superbike race. Kevin McKee put on a dominant performance aboard his Kawasaki Z1, putting in a fast lap that was nine seconds quicker than second-placed Paul Kiefer’s best. Peter Hokenstad secured the final podium spot on his Kawasaki KZ 1000, just edging fourth-placed Andrew Gray.

In the 400 classes, we saw a new winner. Rocco Landers opted to sit out Round 5, giving others a chance to get their hands on a big trophy. That chance was snatched up in all four races by Marc Edwards. Edwards dominated the first event of the weekend, 400 Superbike, and never broke stride. Nik Thompson, Brian Bartlow, Brenden Ketelsen, and Paul Johnson all tasted the podium, but no one could shake Edwards.

On the 600s the weekend belonged to none other than AFM president Berto Woolridge. “El Prez” would take four wins, and a second-place finish in 600 Superstock behind the supremely talented Valentin Debise. Debise also got his hands on the 600 Superbike trophy, ahead of Graves Motorsports teammate Braeden Ortt. Ortt struggled with issues throughout the weekend but appeared to be pleased with his second-place finish behind Debise. Ortt announced Monday that he would be making a switch away from Graves Motorsports for the remainder of the season, contesting the final MotoAmerica races of 2019 aboard a Tuned Racing R6, the same bike he campaigned in 2018. There has been no announcement so far in regards to Ortt competing in the final two AFM rounds of the season.

Once again on the big bikes, it would be the same three riders leading the way. The Graves Motorsports duo of Valentin Debise and Andrew Lee were the clear favorites heading into the weekend. Lee was fresh off his MotoAmerica Stock 1000 win at Sonoma two weeks earlier and looked incredibly confident on his ZX10R, as did Debise. Uribe was another story. At AFM Round 4 Uribe suffered a gruesome injury, grinding his arm along the track and subsequently losing several bones from his elbow. Uribe was very clearly not in top form but put in a courageous effort to finish third behind the Graves tandem. Uribe even took the win in Open GP, a race the Kawi pair did not compete in. Uribe was quick to praise his medical team and family, “I can’t even explain how thankful I am to my doctors, family, and sponsors for helping me get back on a bike just five weeks after a major elbow reconstruction. We went from having a six-month recovery, to racing a motorcycle in less than one third the time”

Lee would come out on top in two of the three races, with Debise taking the crown in Open Superstock, adding to his two 600 wins to complete the hat-trick. Speaking with Lee at the end of the weekend, he was delighted with his results, “I had a great weekend with the Graves Kawasaki crew. They are getting my ZX10R dialed in. I had a lot of laps this weekend with Valentin Debise; we were both learning from one another. In the two races I won, Open Superbike and Formula Pacific, I led every lap. He threw some good passes at me in FP, but I held him off. In Open Superstock he had better pace, I was right with him and still had a fighting chance, up until the point we hit lapped traffic.”

The AFM will be back in action for Round 6 at Thunderhill Raceway Park September 21-22.

10 Steps To The World’s Best Chassis

0

Featured In the August 2019 Issue of Roadracing World:

      Four decades ago, 500cc Grand Prix race-bikes
started making a lot of power, so tires got bigger and frames got stiffer.
Chasing more horsepower was no longer the biggest deal in motorcycle racing.

      That’s why the 500cc GP chassis of the early 1980s
are a million miles away from today’s ultra-high-tech MotoGP creations, most
especially Suzuki’s GSX-RR, the best-handling racebike on the MotoGP grid.

      Chassis geometry has been refined,
mass-centralization has been improved, machine balance has been perfected, and
chassis flex has become a whole new area of racing science to help bikes corner
faster.

      All these improvements have been demanded by more
horsepower, grippier tires, fiercer brakes, and so on …

–MotoGP Analysis: 10 Steps To The World’s Best Chassis Design, by Mat Oxley


It’s
no longer just about which bike makes the most horsepower. Now, the holy grail of
MotoGP engineers is a motorcycle with a pile of horsepower that’s also stable
on the brakes, arcs through an apex like a slalom skier and plants its fat
Michelin slick hard into the asphalt on corner exit. MotoGP Editor Mat Oxley
looks at the evolution of premier-class chassis engineering in the August 2019 issue

MotoAmerica: Championships On The Line This Coming Weekend At New Jersey Motorsports Park

It’s Nearing Title Time In MotoAmerica Series

Championships On The Line Heading To NJMP

COSTA MESA, CA (September 5, 2019)– While two riders are on the verge of capturing titles in the 2019 MotoAmerica Series, the other three classes are still wide open with gaps ranging from 11 to 35 points – including the premier EBC Brakes Superbike Championship – as the series heads to New Jersey Motorsports Park this weekend for the MotoAmerica Championship of New Jersey.

With his 75-point lead in the Liqui Moly Junior Cup Series, 14-year-old Rocco Landers is the rider facing the least resistance en route to the title and barring catastrophe he will wrap up the championship on Saturday in race one. With his nearest competitor, Dallas Daniels, not scheduled to take part in the last two rounds, Landers leads third-placed Kevin Olmedo by 77 points with 100 points (four races) up for grabs. Thus, if Landers wins on Saturday and Olmedo finishes second, the Ninja400.com/Norton Motorsports/Dr. Farr-backed rider from Oregon will lead by an insurmountable 82 points going into Sunday’s race two.

Landers has won 10 races thus far in 2019 with Daniels (1 win), Olmedo (1 win) and Cameron Jones (1 win) the only others to win races in the class.

The Stock 1000 Championship, meanwhile, is also well within the grasp of Andrew Lee and his Franklin Armory/Graves Kawasaki team. Lee holds down a 48-point lead over Stefano Mesa with three races remaining for that class. The Stock 1000 class will race once this weekend at NJMP and twice in the series finale at Barber Motorsports Park, September 20-22. If Lee wins on Sunday afternoon and Mesa finishes second, Lee will leave New Jersey with a 53-point lead with just 50 points left on the table at Barber.

Lee, the defending Stock 1000 Champion, has won four races in a row and five out of the eight races held prior to NJMP.

The other three classes are still unresolved with the champions likely not crowned until the final race concludes at Barber.

The Twins Cup only has two races left on its 2019 schedule – Sunday’s race at NJMP and the lone race in the finale at Barber. Roadracing World Young Guns’ Alex Dumas has a nine-point lead over The Draik 77’s Draik Beauchamp heading into New Jersey with Michael Barnes and his Quarterley Racing Ducati another 10 points behind in third. And the list of potential spoilers is long and includes defending class champion Chris Parrish and his Ghetto Customs Suzuki who can no longer defend his title but will be hungry to make his mark in the final two races.

Dumas holds the hot hand in the class with three wins in a row and four total for the 2018 Liqui Moly Junior Cup Champion, who has made the jump to the Twins Cup class a successful one.

With four races left on the Supersport schedule, just 20 points separate the top three as the series heads to NJMP. M4 ECSTAR Suzuki’s Bobby Fong leads the way with an 11-point lead over Rickdiculous Racing’s Hayden Gillim, 220-209. Celtic HSBK Racing’s PJ Jacobsen is third, 20 points behind Fong and nine behind Gillim. Fong’s teammate Sean Dylan Kelly, the class rookie who won both races at the last round in Pittsburgh, lurks in fourth place – 45 points out of first.

With his two wins at PittRace, Kelly became the fourth different winner in the class – joining Fong (4 wins), Gillim (5 wins) and Jacobsen (2 wins).

That brings us to the EBC Brakes Superbike class where Yoshimura Suzuki’s Toni Elias leads Monster Energy/Yamalube/Yamaha Factory Racing’s Cameron Beaubier by 35 points with four races (100 points) left to run. Elias has put together a seven-win season with Beaubier winning three races so far. Beaubier’s teammate Garrett Gerloff, meanwhile, has also won three races, but his DNF in race two at PittRace two weeks ago put a damper on his championship aspirations as he now trails Elias by 56 points.

Attack Performance Estenson Racing’s JD Beach, who has won once in 2019, sits fourth in the title chase, just six points better than two-time winner Josh Herrin on the second Yoshimura Suzuki. Herrin, in turn, is just 12 points clear of Westby Racing’s Mathew Scholtz as the battle for fourth in the championship likely won’t be decided until the final race.

M4 ECSTAR Suzuki’s Jake Lewis is coming off his best result of the season at PittRace, the Kentuckian leading several laps early on before ending up fourth in race two. Lewis is currently seventh in the championship, 22 points behind Scholtz and 34 points ahead of eighth-placed Jake Gagne on the Scheibe Racing BMW.

Omega Moto’s Cameron Petersen is just a single point behind Gagne in ninth and 13 points ahead of FLY Racing ADR Motorsports’ David Anthony, the Australian rounding out the top 10 heading to New Jersey.

NJMP Fast Facts…

With his race-two win at PittRace two weeks ago, Toni Elias now has 32 AMA Superbike wins on his resume. And that mark matches the MotoAmerica Superbike win total of 32 for Cameron Beaubier. Beaubier, however, won three AMA Superbike races before MotoAmerica took over the series and that gives him 35 total victories in the class.

Those 35 wins puts Beaubier third on the all-time AMA Superbike win list behind Mat Mladin (82) and Josh Hayes (61). Elias, meanwhile, is now tied with Miguel Duhamel for fourth with his 32 wins. Ben Spies, Fred Merkel, Nicky Hayden, Wayne Rainey and Eric Bostrom round out the top 10 on the all-time win list.

Elias has an opportunity to equal or surpass his championship-winning, 10-race-win season of 2017 with victories in the four races left in the 2019 MotoAmerica Series. Elias has seven wins going into NJMP and winning out would give him 11 victories on the year.

With his 10th win of the season coming in race one at PittRace, 14-year-old Rocco Landers equaled the win total set last year by 2018 Liqui Moly Junior Cup Champion Alex Dumas. The rider with the next highest total of wins in the class is Ashton Yates with three wins. Dumas, meanwhile, with his four Twins Cup wins this season, has moved ahead of 2018 Twins Cup Champion Chris Parrish as the win leader in that class.

Westby Racing’s Mathew Scholtz earned pole position for last year’s Superbike races at NJMP with his 1:38.154 set during the Superpole session. As is the norm for MotoAmerica’s two-day events, Superpole won’t be held this year at NJMP. The grid will be set based on lap times from the two qualifying sessions on Saturday.

Superbike race one a year ago was won by Josh Herrin over Scholtz and Beaubier in dominating fashion in precarious conditions. Herrin, who is now on the Yoshimura Suzuki team, rode the Attack Performance/Herrin Compound Yamaha YZF-R1 to a 37-second victory over Scholtz. Cameron Beaubier emerged victorious in an extremely wet race two, besting Roger Hayden by 13.6 seconds with Toni Elias finishing third. The victory, his eighth of the year, wrapped up a third championship for Beaubier.

Hayden Gillim and JD Beach split Supersport wins at NJMP a season ago, with Beach’s runner-up finish in race one enough to earn him his second MotoAmerica Supersport Championship. Beach is now in the EBC Brakes Superbike Championship and Gillim is only 11 points behind Bobby Fong in the 2019 Supersport title chase.

El Salvador’s Kevin Olmedo won the first Liqui Moly Junior Cup race of his career a year ago at NJMP in race one; Alex Dumas ended up on top in race two and that earned him the class championship.

Tawfik Khalil was a surprising winner in the Stock 1000 race last year at NJMP; and Kris Turner won the Twins Cup race after beating Brian McGlade by just .003 of a second.

World Superbike: Autodromo Internacional Do Algarve To Host 400th WorldSBK Round

WorldSBK set to celebrate 400th round in Portugal

A landmark achievement for the WorldSBK championship this weekend, as Portimao will be the 400th round in the history of the championship

The MOTUL FIM Superbike World Championship heads to the Autodromo Internacional do Algarve in Portugal for the Acerbis Portuguese Round this weekend for what is already, a historic weekend in the history of the championship. This weekend will mark the 400th WorldSBK round since the championship began back in 1988 at the famous Donington Park circuit. And since that first round took place, we have seen incredible action…

Famous names such as Davide Tardozzi, Marco Lucchinelli, Bubba Shobert and Joey Dunlop lined up on the grid for the first ever round of World Superbike, with an array of machinery and nationalities forming a truly international grid. Today, that legacy lives on, with 10 different countries from three continents competing against each other, across five different factory manufacturers.

Since 1988, there have been some iconic championship-defining moments. At the 100th round, Pierfrancesco Chili won at home at Monza in 1996, after a dramatic final lap. At the 250th WorldSBK event, it was Carlos Checa’s turn to rise to the occasion at the all-new Miller Motorsport Park in Utah in 2008, taking not just his first win but a double.

To add to the occasion of the 400th WorldSBK round, it will be Portimao’s 11th occasion hosting the world’s fastest production-based championship, with a recent contract extension seeing the popular Portuguese venue on the calendar until 2022. This extension secures Portimao in continuing to showcase exciting and memorable moments in WorldSBK, like it has done before.

In 2008, Troy Bayliss completed cleaned up with what would be his last poles, wins and fastest laps in WorldSBK, and what was at the time, his swansong round. In 2009, Ben Spies took a dramatic championship win from Noriyuki Haga, snatching it from the Japanese rider in Race 1 and confirming his title success in Race 2. It was also the first WorldSBK round for Jonathan Rea, who enters his 135th round this weekend.

This year, the WorldSBK title fight is still on, with Alvaro Bautista (ARUBA.IT Racing – Ducati) looking to overcome Jonathan Rea (Kawasaki Racing Team WorldSBK) on his first time at Portimao. In WorldSSP, the BARDAHL Evan Bros. WorldSSP Team duo of Randy Krummenacher and Federico Caricasulo continue to fight, whilst the championship could be decided in WorldSSP300.

Moto2 World Championship: PETRONAS Sprinta Racing Signs Xavi Vierge For 2020

Xavi Vierge joins expanded PETRONAS Sprinta Racing for 2020

Spanish rider will make the move to enlarged PETRONAS Sprinta Racing squad for 2020 Moto2 World Championship

05 September 2019

Three-time Moto2 podium finisher and former European Moto2 championship runner-up Xavi Vierge will join a two-rider PETRONAS Sprinta Racing line-up for 2020, in the squad’s third year of contesting the Moto2 World Championship.

Vierge, 22, from Barcelona, Spain, was most recently on the podium in Argentina and Australia last season where he finished second and third respectively. Next year will be his fifth full season of Moto2 on the international stage.

The 2020 Moto2 season will get underway in March next year, with the opening round at the Qatar Grand Prix provisionally scheduled for 8th March.

Razlan Razali – Team Principal

“For PETRONAS Sprinta Racing the signing of Xavi Vierge is an exciting development. Firstly, he is a quick and well-proven rider who is capable of regular podium performances. Secondly, he will be one of two riders for us in Moto2 as we expand our squad. PETRONAS Sepang Racing Team will have two riders each in Moto3, Moto2 and MotoGP next year. We know it’s been a tough Moto2 season for us in 2019 and we’re hoping that Khairul Idham Pawi will be fully recovered and racing alongside Xavi next season.”

Johan Stigefelt – Team Director

“We’ve brought Xavi into the team as we know he’s a fast rider and we believe he will be able to help us achieve better results in Moto2. Xavi has a lot of experience, and we think he will flourish within our set-up. He’s the right rider to help us grow together in this category and will be the perfect team leader for our two-bike squad next year. This year has been a difficult season for us in Moto2, but with two bikes and a rider of Xavi’s calibre on one of them, we’re expecting better things from 2020.”

Xavi Vierge

“I’m really happy and I can’t wait to get started with the project. PETRONAS Sprinta Racing are amazing; they’re already fighting for wins in Moto3 and MotoGP and I hope I can add Moto2 to that list next year. The potential is really high, I know a lot of the crew, and I feel like they already believe that we can win together. I’m very thankful for everyone who helped make this opportunity happen and I can’t wait to get started. The first target will be to complete really strong winter tests so we can start in Qatar ready to compete for the top positions. The team have the right attitude and I know we can do well.”

MotoAmerica: Braeden Ortt Switches From Graves Kawasaki To Tuned Racing Yamaha For Remainder Of 2019 Supersport Championship

Attention race fans! Tuned Racing is proud to announce that we will be fielding 2 premier 600 Supersport riders for the last rounds of the MotoAmerica series.

Team manager Alex Eisner was instrumental in putting this deal together and he is extremely excited.

“Bryce and Braeden riding together has been a fantasy of mine for years and now it is becoming a reality,” said Alex Eisner

“I had a great time helping to develop the Kawasaki ZX-6R, but I’m very excited to finish my season on a bike I’m familiar with and a team that I’ve had so many great memories with,” said Braeden Ortt.

“As a team we have been very fortunate to have worked with some very talented riders over the years. I can tell you that Braeden Ortt is one of those riders and he belongs in the front! Anyone that knows me, knows that my riders become family. With the advancements Bryce Prince has made this year and the addition of Braeden we are bound to put on a show and run up front,” said Mike Pond.

Quick Look: Yamaha Tracer 900 GT, A Great Sport-Tourer

Featured In the August 2019 Issue of Roadracing World:

      It’s been a few years since Yamaha decided to unify
model names worldwide, relabeling what were the U.S.-market models with
European market names.

      After doing that, the company refined what was the
FJ-09 in the U.S. and re-named it the Tracer 900, and added an upgraded Tracer
900 GT. The result is a convenient sport tourer capable of covering a lot of
miles in comfort.

      The Tracer 900 and Tracer 900 GT share the FJ-09’s
original liquid-cooled, fuel-injected, DOHC, inline three-cylinder engine, with
a displacement of 847cc coming from a bore and stroke of 78.0mm x 59.1mm.

      Compression ratio is unchanged at 11.5:1, and the
engine continues to feature cylinders offset from the crankshaft to reduce
friction on the power stroke, fracture-split connecting rods, velocity stacks
with staggered lengths, and a “crossplane concept” crankshaft with uneven power
pulses to deliver more linear torque …

–Quick Look: Yamaha Tracer 900 GT, by David Swarts


Yamaha’s
magnificent inline three-cylinder engine powers a lot of the company’s
vehicles, and the Tracer models put that engine prowess to use in a wide
variety of roles. It’s a tourer that can sport quite nicely, thank you very
much. Read all about Yamaha’s versatile, functional and rapid do-it-all Tracer

AFM: Andrew Lee Takes Another Formula Pacific Race Victory, At Sonoma Raceway

The AFM was back in action Labor Day long weekend at its spiritual home, Sonoma Raceway, for Round Five of the AFM Championship.

Jayson Uribe rushed back from a gruesome injury last round at Thunderhill to keep his AFM number one plate hopes alive. Current AFM number one, Andrew Lee, fresh off his MotoAmerica win at Sonoma just two weeks ago, put up two wins and a strong second-place finish to ensure the title fight continues back to Thunderhill. Lee’s Graves Motorsports teammate, Frenchman Valentin Debise also impressed, securing a hat-trick of wins at Sonoma.

After four rounds split between Thunderhill and Buttonwillow, the AFM rolled into Sonoma for its only stop at the famed race track. Every year Sonoma is an exceptional round for the AFM. The track on Sears Point is a place where many riders make their debut, and many more veterans dust off the leathers for a comeback. This year the throwback feel was stronger than ever, with the AFM teaming up with CSRA to bring Vintage Superbike racing back to the Bay Area. The grids were stacked and great times were had by all, both young and not so young.

The weekend’s racing kicked off with the marquee CSRA Vintage Superbike race. Kevin McKee put on a dominant performance aboard his Kawasaki Z1, putting in a fast lap that was nine seconds quicker than second-placed Paul Kiefer’s best. Peter Hokenstad secured the final podium spot on his Kawasaki KZ 1000, just edging fourth-placed Andrew Gray.

In the 400 classes, we saw a new winner. Rocco Landers opted to sit out Round 5, giving others a chance to get their hands on a big trophy. That chance was snatched up in all four races by Marc Edwards. Edwards dominated the first event of the weekend, 400 Superbike, and never broke stride. Nik Thompson, Brian Bartlow, Brenden Ketelsen, and Paul Johnson all tasted the podium, but no one could shake Edwards.

On the 600s the weekend belonged to none other than AFM president Berto Woolridge. “El Prez” would take four wins, and a second-place finish in 600 Superstock behind the supremely talented Valentin Debise. Debise also got his hands on the 600 Superbike trophy, ahead of Graves Motorsports teammate Braeden Ortt. Ortt struggled with issues throughout the weekend but appeared to be pleased with his second-place finish behind Debise. Ortt announced Monday that he would be making a switch away from Graves Motorsports for the remainder of the season, contesting the final MotoAmerica races of 2019 aboard a Tuned Racing R6, the same bike he campaigned in 2018. There has been no announcement so far in regards to Ortt competing in the final two AFM rounds of the season.

Once again on the big bikes, it would be the same three riders leading the way. The Graves Motorsports duo of Valentin Debise and Andrew Lee were the clear favorites heading into the weekend. Lee was fresh off his MotoAmerica Stock 1000 win at Sonoma two weeks earlier and looked incredibly confident on his ZX10R, as did Debise. Uribe was another story. At AFM Round 4 Uribe suffered a gruesome injury, grinding his arm along the track and subsequently losing several bones from his elbow. Uribe was very clearly not in top form but put in a courageous effort to finish third behind the Graves tandem. Uribe even took the win in Open GP, a race the Kawi pair did not compete in. Uribe was quick to praise his medical team and family, “I can’t even explain how thankful I am to my doctors, family, and sponsors for helping me get back on a bike just five weeks after a major elbow reconstruction. We went from having a six-month recovery, to racing a motorcycle in less than one third the time”

Lee would come out on top in two of the three races, with Debise taking the crown in Open Superstock, adding to his two 600 wins to complete the hat-trick. Speaking with Lee at the end of the weekend, he was delighted with his results, “I had a great weekend with the Graves Kawasaki crew. They are getting my ZX10R dialed in. I had a lot of laps this weekend with Valentin Debise; we were both learning from one another. In the two races I won, Open Superbike and Formula Pacific, I led every lap. He threw some good passes at me in FP, but I held him off. In Open Superstock he had better pace, I was right with him and still had a fighting chance, up until the point we hit lapped traffic.”

The AFM will be back in action for Round 6 at Thunderhill Raceway Park September 21-22.

10 Steps To The World’s Best Chassis

Featured In the August 2019 Issue of Roadracing World:

      Four decades ago, 500cc Grand Prix race-bikes
started making a lot of power, so tires got bigger and frames got stiffer.
Chasing more horsepower was no longer the biggest deal in motorcycle racing.

      That’s why the 500cc GP chassis of the early 1980s
are a million miles away from today’s ultra-high-tech MotoGP creations, most
especially Suzuki’s GSX-RR, the best-handling racebike on the MotoGP grid.

      Chassis geometry has been refined,
mass-centralization has been improved, machine balance has been perfected, and
chassis flex has become a whole new area of racing science to help bikes corner
faster.

      All these improvements have been demanded by more
horsepower, grippier tires, fiercer brakes, and so on …

–MotoGP Analysis: 10 Steps To The World’s Best Chassis Design, by Mat Oxley


It’s
no longer just about which bike makes the most horsepower. Now, the holy grail of
MotoGP engineers is a motorcycle with a pile of horsepower that’s also stable
on the brakes, arcs through an apex like a slalom skier and plants its fat
Michelin slick hard into the asphalt on corner exit. MotoGP Editor Mat Oxley
looks at the evolution of premier-class chassis engineering in the August 2019 issue
of Roadracing World!
