Chris Ulrich: Adventures Of An Ex-Racer—Riding In The Wet And Dry At Sonoma
Chris Clark had a dream start to the 2025 FIM Yamaha R3 BLU CRU World Cup at Portimão in Portugal this past weekend, taking a win and a third place in the two nine lap races to lead the championship standings after the opening round. In doing so he becomes the first North American to ever win in the series!
Starting from the front row of the grid after setting the third fastest time in Superpole, the American teen soon hit the front when the lights went out for race one on Saturday and after demonstrating some incredible skill to place himself in the right place as the leading group entered the final couple of laps of the race it was clear he would be a podium contender. With a lap to go Clark made a final attack for glory and began to pull away from his pursuers. Exiting the final corner perfectly he crossed the line to take victory by 0.110s.

Sunday’s second race saw the Accolade SMRZ BGR rider start from eleventh on the grid, but an aggressive opening two laps soon saw him at the head of the pack for the second race running. A group of ten fought back and forth with Chris once again racing smart to ensure he was in the perfect place to maximise slip stream. The #5 rider was lucky to stay aboard after he was hit from behind in an incident that saw two of the leading riders crash out, but he soon regrouped and once again it was a last lap shoot out to decide the podium. A photo finish between four riders at the flag saw him classified third. Elated to lead the World Cup standings after the opening round Chris heads home to the USA fully focused on round two in Italy in June and confident of challenging for the title.

Chris Clark:“What a start to the season. To start the day on Saturday with no warm up was something new for me but honestly, I liked just getting straight into it. I made a good start in Race one and led early on. I rode smart and defensive when I needed to but also made some cool overtakes. At one point I was shuffled back to ninth but past a bunch of riders to move back into second in one corner. Going into the final lap I knew I could lead out of the final corner and lead it over the line, and it worked out perfectly. Race two was awesome. It was a little bit of a challenge to get up to the front after starting eleventh, but I made it by lap two which I am happy about. I was able to fight for the win after making some aggressive overtakes and leading many laps. It’s a shame that on the last lap the other riders were able to benefit from my slipstream as I was leading but I managed to take another podium which is great. Overall, it couldn’t have been much better. It was a great weekend for me and the team, and we are leading the championship heading to Misano. I want to thank everyone who is supporting me it means the world.”

Fatal State Fair Accident Provides Insight into Future
Motorcyclists Involved in Bumper-car Mishap
Many of you saw the news of the fatal Cook County Fair bumper-car incident where a group of motorcycle riders paid $1.50 to drive the electric bumper-cars for 10 minutes.
From the Cook County Chieftain newspaper: “A group of five crotch-rocket pilots joined the usual mix of kids for a 10-minute bumper-car session at the Cook County Fair last night. At the seven-minute mark a fatal accident occurred when one of the motorcyclists accidentally touched his head against the electrified floor of the bumper-car arena, immediately shocking himself with 5,400 volts.”
That was me. I was trying to get the bumper car to turn better by using my body.
Apparently I lost my balance and my heart was shocked to a standstill with 5,400 volts, but I don’t remember it much. All I know is that I woke up in a town called Purgatory in a long line waiting to talk to “Pete,” according to his name tag.
By the time I reached Pete, he was tired. I gave him my paperwork and he mistook the capital “I” (i) of my last name for a lower-case “l” (L). This happens all the time. “Nick Lenatsch, Nick Lenatsch…” he muttered to himself. “I can’t find any naughty information on you, so please come in.” He swung open a big gate, clapped me on the back, and noticed my “I’d rather push my motorcycle than drive a car” T-shirt and said, “Motorcycle rider? Most all you riders make it up here. Take a left here and follow the signs. The Boss is usually over there anyway.”
I didn’t need the signs because I could hear a bike revving, and as I got closer it sounded more and more like a multi-cylinder two-stroke getting warmed up. I had heard it a thousand times; I turned the corner to finally see the bike. Imagine my shock when I came face to face with God and Jarno Saarinen!
I had never met Jarno or God, but they are both very recognizable. God was holding his beard away from the spinning dry clutch as he crouched next to what appeared to be Valentino Rossi’s championship-winning 2001 NSR500. Jarno was on the other side, blipping the throttle and the thing sounded tight and right.
They both looked over and waved, so I said hello and added, “Man, sounds like you’ve got the jetting perfect!”
God laughed and shook his head. “No, up here everything is fuel-injected.” I then noticed the laptop Jarno held.
“But I thought fuel-injection limited a two-stoke’s ability to rev,” I exclaimed.
Jarno shook his head again. “That excuse is just being put forth by the four-stroke manufacturers who have invested so much time and money in a weak, flawed product that is slow…and difficult and expensive to rebuild.”
God reached up and punched the kill switch, shutting down the four-cylinder 500. In the sudden silence I could hear another smoker running on what sounded like a dirt track. The bike wasn’t being shifted, just run to redline in a single gear then shut-down for the corner. I could hear the engine working as the tire spun on the exits and we all listened for a minute because it was truly heavenly music.
God saw me listening and explained, “Oh, that’s Nicky Hayden and a bunch of his buddies—jokers like Ricky Graham. Nicky started dirt tracking on our two-strokes, and, man, is he glad to be back on what he calls ‘a real engine.'”
“Yep, those guys have just about worn out that track!” I spun around at the sound of the English accent, and there sat Barry Sheene and Mike Hailwood, both in riding gear.
Before I could think, I blurted out, “After all your shenanigans, they let you in here, Barry?” His wild playboy life was well documented, yet here he was, in heaven.
“They did,” he answered. “Almost all motorcycle riders get to heaven.”
“So maybe there’s hope for Kenny Roberts Senior?” I asked.
“Oooh, I don’t know if I’d go that far.” Hailwood looked skeptical too, and God gave a little shake of his head as if to say, “Dat boy’s pretty crazy.” But then he added, “We might have some room for KR… After all, somebody’s gotta school Revvin’ Kevin Rentzell and the boys.”
But then I was distracted by the bikes Sheen and Hailwood were sitting on: A Britten and a Czysz. I’ve been lucky enough to ride them both, but these models looked different and I hurried in for a closer look. Sure enough, big fat expansion chambers signaled two-stroke engines in each bike. “What the hell?” I exclaimed.
“OK, watch your language,” Hailwood said with a furtive glance at God but then continued, “John and Michael never wanted heavy four-stroke engines in their chassis, so now they have a chance to do these bikes correctly. John built a 800cc V-Twin two-stroke and Michael did his offset Inline-4 trick to create a 990cc 5-degree V-4 smoker.”
“They’re both here?” I asked.
“Oh, yeah,” God confirmed. “They’re thick as thieves and have a shop at the track.”
“You have your own track?”
God hires the best pavers… -istockphoto
God looked at me and shook his head at my silly question. He pointed to his “God” name tag and I blushed, apologizing, “Sorry, just a bit overwhelmed.”
He continued. “The track was easy. I took Elkhart Lake, Mid-Ohio, Barber, and Laguna Seca and combined the best parts of each. Jarno insisted on three corners from Spa, the final turn from Monza. Kids like Tommy Aquino and Dane Westby have never ridden those European tracks, so they figuratively and literally are in heaven. Of course, we took that silly add-on chicane out of Elkhart.”
“Yeah,” piped in Barry. “Remember Marco’s reaction when you showed him videos of that chicane?”
“Simoncelli?” I asked.
Barry nodded. “Yep, he couldn’t believe they ruined the kink at Elkhart Lake with that chicane and about had a heart attack when he saw what Road Atlanta did to the Gravity Cavity. Marco has the lap record here so far, on the Czysz V, and has led us to victory in the series.”
“You have a racing series?” I had turned back to God.
He was nodding and smiling. “Yes, we do. Four times a year we travel south to Hell and run on their track against their best. Hell’s track is made up of the pavement from the old Nelson Ledges and the retaining walls from Watkins Glen with the weather of Willow Springs in August and the neighbors of Laguna Seca. We also race here four times a year.”
Hell’s track…and you’re subjugated to four-strokes! -istockphoto
“How’s it going?”
“Oh, we’re undefeated since the series began in 1907.”
“Wow, congratulations,” I gasped. “That’s amazing. And it’s because good always triumphs over evil, right?”
Everybody laughed! “No,” answered God. “They’ve only got normally aspirated four-strokes in Hell.”
God let me ride Rossi’s NSR back to the track shop where I reunited with Britten and Czysz. They swept me into the work area and each still possessed that childlike excitement that had been so unique when I first met them on Earth. Merlyn Plumlee had an engine apart on the bench and then Nicky rolled in his smoker dirt tracker and gave me a dusty hug.
“How is that thing?”
“Man,” he drawled, “it’s the real deal. I don’t have any regrets, but I’d sure like to run this thing at Del Mar. My dad tunes it…we’d kick Tommy’s butt.” Trademark Nicky Hayden smile.
By this time, God, Jarno, Sheene and Hailwood had joined us and they started talking about how God’s fuel-injected two-strokes would have been game-changing on Earth.
“Do they have traction control?” I asked as I examined one of the race Brittens.
“No,” God answered. “Traction and wheelie control were relegated to Hell’s team.”
“Thank God,” Jarno blurted. Then blushed and apologized to God. Everyone laughed when He answered, “You’re welcome.”
I wasn’t laughing and God saw it. “What’s wrong?”
I turned to him and asked the question that had been on my mind since Pete waved me through the gate. “My dad, Bill Ienatsch, died a year ago….do you know of him?”

“Is that how you pronounced Bill’s last name?” Jarno asked. “I always wondered. Yes, Bill has re-engineered the wash racks and completely evolved the waxing and polishing systems we use, including changing us from a liquid wax to a paste carnauba. He and Schwarzi—Larry Schwarzbach—are either cleaning something or out riding.”
I was nodding and smiling. “So he really is in heaven. Where is he now?”
“He’s at lunch at our version of Salt Lake City’s East Canyon, one of your dad’s favorite rides…except up here there’s no gravel, cops, or oncoming traffic texting selfies,” Jarno continued. I could see Jarno and my dad got along well.
But God had walked closer to me. “Nick, did you say your last name was Ienatsch or Lenatsch?”
I gulped nervously, realizing my mistake. “Ienatsch.” I lie all the time, but it seemed impossible to lie to God right there in heaven.
God pulled an iPad out of his coveralls.
He double-checked something on the iPad then gripped my arm firmly. “Sorry, son, you’re not supposed to be here.” He quick-walked me over to a previously invisible membrane and threw me through it, yelling, “You’re going back to Earth for a little while longer, and then I’m afraid you’re going to be racing four-strokes with traction and wheelie control after that!”
As I tumbled through the atmosphere I screamed back up to God, “Wait! Pete and Barry said most motorcyclists get into heaven!”
Through the clouds I heard God’s voice reply, “Yeah, but you’re a journalist!”
I landed with a thud on the bumper-car arena floor with a sweating EMT kneeling over me pumping my chest. I could feel the burn on my forehead as his sweat dripped into the fresh wound. Kids were gathered around and somebody said, “He ain’t no Marc Márquez. He didn’t drag his elbow until after his forehead hit the floor.” But that hurtful statement hardly registered. All I could think about was: I better race AHRMA as much as possible before I die!
Happy April Fools Day to all riders! -E-tech Photo
Even a master manipulator can get it wrong. Race Direction can get it right. And sometimes everybody just gets lucky.
After picking through the bones of Sunday’s MotoGP starting grid confusion at the Red Bull Grand Prix of The Americas, those are my key takeaways.
Nobody gets to be an eight-time World Champion just by being fast. Marc Marquez is always thinking and plotting–his mid-season off-track maneuvers last year got him the most desirable ride in the paddock and left many of his strongest competitors worse off.
Last Sunday, the Moto2 race was wet, and punished riders who chose slicks–American Joe Roberts among them. And as the MotoGP bikes were sent to the grid for the Grand Prix race, it was still drizzling on and off. But it was hot, so the track was drying; then it would drizzle and wet the track again. Most teams went to the grid on rain tires.

It is critical to understand that changing to a rain setup on a modern MotoGP racebike is not simple. Teams were swapping fork springs on the grid. Just pulling off the front wheel requires the removal of the brake discs and sensors. And the crew has to do this in a tiny cordoned-off area with a pile of tools, a starter, tire warmers, stands, and other equipment, and with a bunch of media types trying to do broadcasts or take pictures. There are often-clueless celebrities and VIPs milling around trying to get the perfect selfie. It is a crowded, confusing place for the riders and for the crew to make complicated changes to a very complicated racebike and to plot strategy. It’s easy for a well-meaning journalist to take a wrong step and accidently knock a rider sideways (sorry, Marc!)
As the civilians were clearing off the grid, Marquez was plotting. He was watching the weather and knew that rain tires were not the right choice, and that there was no time to switch the bike back to slicks. So he told the team to prep the backup bike in the garage, and just before the three-minute board was displayed he planned to bolt for pit lane, leaving the rain-tire-shod bike, the crew, and the stuff on the grid.
Other riders were thinking the same thing. Some were staring at the sky, knowing their team had made the wrong call on tires. Some were watching Marquez carefully when he oh-so-casually got off his bike and stood next to it. When he ran for the garage, it started a stampede. Half the other riders followed in his footsteps. Some said later they didn’t even know why they were running, but they have a deep respect for Marc’s machinations, and they figured that Marquez had figured out something.

Problem was, Marquez was wrong. To be fair, his team wasn’t exactly clear on the rules, either. Marquez thought that if he swapped bikes before the three-minute board was displayed he’d start from the back of the grid, which he would have been OK with. But he actually would have had a ride-through penalty, according to the rules. After a 2018 start-line fiasco in Argentina, the rules had changed to severely penalize MotoGP riders who swapped bikes to go from rains to slicks (or vice-versa) after the sighting lap. And the rains clearly would not have lasted the distance on Sunday. The riders on rain tires would have had to do a bike swap mid-race, costing them just as much time as a ride-through.
Marquez also thought that if 10 riders followed him, the rules required Race Direction to delay the proceedings and start everyone from the grid. But that only applies if 10 or more riders would be starting from pit lane–for example, if riders pulled in after the warmup lap and then headed back out when the race began. In reality, there was the potential for half the field to have ride-through penalties!
So with three minutes left before the start of the race, half the riders were running for the garages. (Poor Jack Miller gets to the Pramac Yamaha garage and found out that his backup machine was also on rains!) There were motorcycles abandoned on the grid. Maverick Vinales’ KTM shut itself off. There are bikes everywhere, crew members everywhere, stuff everywhere.

And this is where Race Director Mike Webb blew the whistle and brought proceedings to a halt.
Regardless of what the rules said, the situation was escalating into something dangerous. Riders who swapped bikes would have been charging down Pit Lane to get to the exit before it was closed, right at the time when crew members were trying to pull abandoned bikes and equipment off the grid. Motorsport history is littered with tragedies that have happened in Pit Lane. And being on Pit Lane just before the start of a MotoGP race gives a real perspective of just how chaotic it is under the best of circumstances. It is really easy to understand how easily someone could get hurt.
Webb did exactly what a Race Director should do–monitor a situation and take appropriate action.
Ironically, it was the chaos that Marquez sparked that ultimately worked to his benefit. Because Webb stopped everything on safety grounds and called for a quick restart, the teams had time to work on the bikes and everyone went with slicks and dry set-ups. And the grid reformed in its original configuration as per the restart rules. “They were very lucky to get away with that,” Webb said later.
At the end of the day, the three riders who initially gambled on slicks–Brad Binder, Enea Bastiannini and Ai Ogura–weren’t happy that they didn’t get to enjoy the benefits of their decision. But Binder’s bike shut itself off. Bastiannini finished seventh, more than 12 seconds down, and Ogura was ninth, more than 16 seconds back. If Marquez or Francesco Bagnaia had to serve a ride-through penalty or switch bikes, Bastiannini or Ogura may or may not have been able to hold them off. But it is likely that Bastiannini or Ogura would have finished higher than they did. So yes, the decision to stop proceedings did harm them.
Webb says the rules will be re-assessed in the wake of Sunday’s drama. And if there are penalties to be assessed, by all means, assess them. But Webb’s snap decision meant that I’m not here today writing a story about a pit lane tragedy. That’s a win in my book.

Chris Clark had a dream start to the 2025 FIM Yamaha R3 BLU CRU World Cup at Portimão in Portugal this past weekend, taking a win and a third place in the two nine lap races to lead the championship standings after the opening round. In doing so he becomes the first North American to ever win in the series!
Starting from the front row of the grid after setting the third fastest time in Superpole, the American teen soon hit the front when the lights went out for race one on Saturday and after demonstrating some incredible skill to place himself in the right place as the leading group entered the final couple of laps of the race it was clear he would be a podium contender. With a lap to go Clark made a final attack for glory and began to pull away from his pursuers. Exiting the final corner perfectly he crossed the line to take victory by 0.110s.

Sunday’s second race saw the Accolade SMRZ BGR rider start from eleventh on the grid, but an aggressive opening two laps soon saw him at the head of the pack for the second race running. A group of ten fought back and forth with Chris once again racing smart to ensure he was in the perfect place to maximise slip stream. The #5 rider was lucky to stay aboard after he was hit from behind in an incident that saw two of the leading riders crash out, but he soon regrouped and once again it was a last lap shoot out to decide the podium. A photo finish between four riders at the flag saw him classified third. Elated to lead the World Cup standings after the opening round Chris heads home to the USA fully focused on round two in Italy in June and confident of challenging for the title.

Chris Clark:“What a start to the season. To start the day on Saturday with no warm up was something new for me but honestly, I liked just getting straight into it. I made a good start in Race one and led early on. I rode smart and defensive when I needed to but also made some cool overtakes. At one point I was shuffled back to ninth but past a bunch of riders to move back into second in one corner. Going into the final lap I knew I could lead out of the final corner and lead it over the line, and it worked out perfectly. Race two was awesome. It was a little bit of a challenge to get up to the front after starting eleventh, but I made it by lap two which I am happy about. I was able to fight for the win after making some aggressive overtakes and leading many laps. It’s a shame that on the last lap the other riders were able to benefit from my slipstream as I was leading but I managed to take another podium which is great. Overall, it couldn’t have been much better. It was a great weekend for me and the team, and we are leading the championship heading to Misano. I want to thank everyone who is supporting me it means the world.”

Fatal State Fair Accident Provides Insight into Future
Motorcyclists Involved in Bumper-car Mishap
Many of you saw the news of the fatal Cook County Fair bumper-car incident where a group of motorcycle riders paid $1.50 to drive the electric bumper-cars for 10 minutes.
From the Cook County Chieftain newspaper: “A group of five crotch-rocket pilots joined the usual mix of kids for a 10-minute bumper-car session at the Cook County Fair last night. At the seven-minute mark a fatal accident occurred when one of the motorcyclists accidentally touched his head against the electrified floor of the bumper-car arena, immediately shocking himself with 5,400 volts.”
That was me. I was trying to get the bumper car to turn better by using my body.
Apparently I lost my balance and my heart was shocked to a standstill with 5,400 volts, but I don’t remember it much. All I know is that I woke up in a town called Purgatory in a long line waiting to talk to “Pete,” according to his name tag.
By the time I reached Pete, he was tired. I gave him my paperwork and he mistook the capital “I” (i) of my last name for a lower-case “l” (L). This happens all the time. “Nick Lenatsch, Nick Lenatsch…” he muttered to himself. “I can’t find any naughty information on you, so please come in.” He swung open a big gate, clapped me on the back, and noticed my “I’d rather push my motorcycle than drive a car” T-shirt and said, “Motorcycle rider? Most all you riders make it up here. Take a left here and follow the signs. The Boss is usually over there anyway.”
I didn’t need the signs because I could hear a bike revving, and as I got closer it sounded more and more like a multi-cylinder two-stroke getting warmed up. I had heard it a thousand times; I turned the corner to finally see the bike. Imagine my shock when I came face to face with God and Jarno Saarinen!
I had never met Jarno or God, but they are both very recognizable. God was holding his beard away from the spinning dry clutch as he crouched next to what appeared to be Valentino Rossi’s championship-winning 2001 NSR500. Jarno was on the other side, blipping the throttle and the thing sounded tight and right.
They both looked over and waved, so I said hello and added, “Man, sounds like you’ve got the jetting perfect!”
God laughed and shook his head. “No, up here everything is fuel-injected.” I then noticed the laptop Jarno held.
“But I thought fuel-injection limited a two-stoke’s ability to rev,” I exclaimed.
Jarno shook his head again. “That excuse is just being put forth by the four-stroke manufacturers who have invested so much time and money in a weak, flawed product that is slow…and difficult and expensive to rebuild.”
God reached up and punched the kill switch, shutting down the four-cylinder 500. In the sudden silence I could hear another smoker running on what sounded like a dirt track. The bike wasn’t being shifted, just run to redline in a single gear then shut-down for the corner. I could hear the engine working as the tire spun on the exits and we all listened for a minute because it was truly heavenly music.
God saw me listening and explained, “Oh, that’s Nicky Hayden and a bunch of his buddies—jokers like Ricky Graham. Nicky started dirt tracking on our two-strokes, and, man, is he glad to be back on what he calls ‘a real engine.'”
“Yep, those guys have just about worn out that track!” I spun around at the sound of the English accent, and there sat Barry Sheene and Mike Hailwood, both in riding gear.
Before I could think, I blurted out, “After all your shenanigans, they let you in here, Barry?” His wild playboy life was well documented, yet here he was, in heaven.
“They did,” he answered. “Almost all motorcycle riders get to heaven.”
“So maybe there’s hope for Kenny Roberts Senior?” I asked.
“Oooh, I don’t know if I’d go that far.” Hailwood looked skeptical too, and God gave a little shake of his head as if to say, “Dat boy’s pretty crazy.” But then he added, “We might have some room for KR… After all, somebody’s gotta school Revvin’ Kevin Rentzell and the boys.”
But then I was distracted by the bikes Sheen and Hailwood were sitting on: A Britten and a Czysz. I’ve been lucky enough to ride them both, but these models looked different and I hurried in for a closer look. Sure enough, big fat expansion chambers signaled two-stroke engines in each bike. “What the hell?” I exclaimed.
“OK, watch your language,” Hailwood said with a furtive glance at God but then continued, “John and Michael never wanted heavy four-stroke engines in their chassis, so now they have a chance to do these bikes correctly. John built a 800cc V-Twin two-stroke and Michael did his offset Inline-4 trick to create a 990cc 5-degree V-4 smoker.”
“They’re both here?” I asked.
“Oh, yeah,” God confirmed. “They’re thick as thieves and have a shop at the track.”
“You have your own track?”

God looked at me and shook his head at my silly question. He pointed to his “God” name tag and I blushed, apologizing, “Sorry, just a bit overwhelmed.”
He continued. “The track was easy. I took Elkhart Lake, Mid-Ohio, Barber, and Laguna Seca and combined the best parts of each. Jarno insisted on three corners from Spa, the final turn from Monza. Kids like Tommy Aquino and Dane Westby have never ridden those European tracks, so they figuratively and literally are in heaven. Of course, we took that silly add-on chicane out of Elkhart.”
“Yeah,” piped in Barry. “Remember Marco’s reaction when you showed him videos of that chicane?”
“Simoncelli?” I asked.
Barry nodded. “Yep, he couldn’t believe they ruined the kink at Elkhart Lake with that chicane and about had a heart attack when he saw what Road Atlanta did to the Gravity Cavity. Marco has the lap record here so far, on the Czysz V, and has led us to victory in the series.”
“You have a racing series?” I had turned back to God.
He was nodding and smiling. “Yes, we do. Four times a year we travel south to Hell and run on their track against their best. Hell’s track is made up of the pavement from the old Nelson Ledges and the retaining walls from Watkins Glen with the weather of Willow Springs in August and the neighbors of Laguna Seca. We also race here four times a year.”
Hell’s track…and you’re subjugated to four-strokes! -istockphoto
“How’s it going?”
“Oh, we’re undefeated since the series began in 1907.”
“Wow, congratulations,” I gasped. “That’s amazing. And it’s because good always triumphs over evil, right?”
Everybody laughed! “No,” answered God. “They’ve only got normally aspirated four-strokes in Hell.”
God let me ride Rossi’s NSR back to the track shop where I reunited with Britten and Czysz. They swept me into the work area and each still possessed that childlike excitement that had been so unique when I first met them on Earth. Merlyn Plumlee had an engine apart on the bench and then Nicky rolled in his smoker dirt tracker and gave me a dusty hug.
“How is that thing?”
“Man,” he drawled, “it’s the real deal. I don’t have any regrets, but I’d sure like to run this thing at Del Mar. My dad tunes it…we’d kick Tommy’s butt.” Trademark Nicky Hayden smile.
By this time, God, Jarno, Sheene and Hailwood had joined us and they started talking about how God’s fuel-injected two-strokes would have been game-changing on Earth.
“Do they have traction control?” I asked as I examined one of the race Brittens.
“No,” God answered. “Traction and wheelie control were relegated to Hell’s team.”
“Thank God,” Jarno blurted. Then blushed and apologized to God. Everyone laughed when He answered, “You’re welcome.”
I wasn’t laughing and God saw it. “What’s wrong?”
I turned to him and asked the question that had been on my mind since Pete waved me through the gate. “My dad, Bill Ienatsch, died a year ago….do you know of him?”

“Is that how you pronounced Bill’s last name?” Jarno asked. “I always wondered. Yes, Bill has re-engineered the wash racks and completely evolved the waxing and polishing systems we use, including changing us from a liquid wax to a paste carnauba. He and Schwarzi—Larry Schwarzbach—are either cleaning something or out riding.”
I was nodding and smiling. “So he really is in heaven. Where is he now?”
“He’s at lunch at our version of Salt Lake City’s East Canyon, one of your dad’s favorite rides…except up here there’s no gravel, cops, or oncoming traffic texting selfies,” Jarno continued. I could see Jarno and my dad got along well.
But God had walked closer to me. “Nick, did you say your last name was Ienatsch or Lenatsch?”
I gulped nervously, realizing my mistake. “Ienatsch.” I lie all the time, but it seemed impossible to lie to God right there in heaven.
God pulled an iPad out of his coveralls.
He double-checked something on the iPad then gripped my arm firmly. “Sorry, son, you’re not supposed to be here.” He quick-walked me over to a previously invisible membrane and threw me through it, yelling, “You’re going back to Earth for a little while longer, and then I’m afraid you’re going to be racing four-strokes with traction and wheelie control after that!”
As I tumbled through the atmosphere I screamed back up to God, “Wait! Pete and Barry said most motorcyclists get into heaven!”
Through the clouds I heard God’s voice reply, “Yeah, but you’re a journalist!”
I landed with a thud on the bumper-car arena floor with a sweating EMT kneeling over me pumping my chest. I could feel the burn on my forehead as his sweat dripped into the fresh wound. Kids were gathered around and somebody said, “He ain’t no Marc Márquez. He didn’t drag his elbow until after his forehead hit the floor.” But that hurtful statement hardly registered. All I could think about was: I better race AHRMA as much as possible before I die!
Happy April Fools Day to all riders! -E-tech Photo
Even a master manipulator can get it wrong. Race Direction can get it right. And sometimes everybody just gets lucky.
After picking through the bones of Sunday’s MotoGP starting grid confusion at the Red Bull Grand Prix of The Americas, those are my key takeaways.
Nobody gets to be an eight-time World Champion just by being fast. Marc Marquez is always thinking and plotting–his mid-season off-track maneuvers last year got him the most desirable ride in the paddock and left many of his strongest competitors worse off.
Last Sunday, the Moto2 race was wet, and punished riders who chose slicks–American Joe Roberts among them. And as the MotoGP bikes were sent to the grid for the Grand Prix race, it was still drizzling on and off. But it was hot, so the track was drying; then it would drizzle and wet the track again. Most teams went to the grid on rain tires.

It is critical to understand that changing to a rain setup on a modern MotoGP racebike is not simple. Teams were swapping fork springs on the grid. Just pulling off the front wheel requires the removal of the brake discs and sensors. And the crew has to do this in a tiny cordoned-off area with a pile of tools, a starter, tire warmers, stands, and other equipment, and with a bunch of media types trying to do broadcasts or take pictures. There are often-clueless celebrities and VIPs milling around trying to get the perfect selfie. It is a crowded, confusing place for the riders and for the crew to make complicated changes to a very complicated racebike and to plot strategy. It’s easy for a well-meaning journalist to take a wrong step and accidently knock a rider sideways (sorry, Marc!)
As the civilians were clearing off the grid, Marquez was plotting. He was watching the weather and knew that rain tires were not the right choice, and that there was no time to switch the bike back to slicks. So he told the team to prep the backup bike in the garage, and just before the three-minute board was displayed he planned to bolt for pit lane, leaving the rain-tire-shod bike, the crew, and the stuff on the grid.
Other riders were thinking the same thing. Some were staring at the sky, knowing their team had made the wrong call on tires. Some were watching Marquez carefully when he oh-so-casually got off his bike and stood next to it. When he ran for the garage, it started a stampede. Half the other riders followed in his footsteps. Some said later they didn’t even know why they were running, but they have a deep respect for Marc’s machinations, and they figured that Marquez had figured out something.

Problem was, Marquez was wrong. To be fair, his team wasn’t exactly clear on the rules, either. Marquez thought that if he swapped bikes before the three-minute board was displayed he’d start from the back of the grid, which he would have been OK with. But he actually would have had a ride-through penalty, according to the rules. After a 2018 start-line fiasco in Argentina, the rules had changed to severely penalize MotoGP riders who swapped bikes to go from rains to slicks (or vice-versa) after the sighting lap. And the rains clearly would not have lasted the distance on Sunday. The riders on rain tires would have had to do a bike swap mid-race, costing them just as much time as a ride-through.
Marquez also thought that if 10 riders followed him, the rules required Race Direction to delay the proceedings and start everyone from the grid. But that only applies if 10 or more riders would be starting from pit lane–for example, if riders pulled in after the warmup lap and then headed back out when the race began. In reality, there was the potential for half the field to have ride-through penalties!
So with three minutes left before the start of the race, half the riders were running for the garages. (Poor Jack Miller gets to the Pramac Yamaha garage and found out that his backup machine was also on rains!) There were motorcycles abandoned on the grid. Maverick Vinales’ KTM shut itself off. There are bikes everywhere, crew members everywhere, stuff everywhere.

And this is where Race Director Mike Webb blew the whistle and brought proceedings to a halt.
Regardless of what the rules said, the situation was escalating into something dangerous. Riders who swapped bikes would have been charging down Pit Lane to get to the exit before it was closed, right at the time when crew members were trying to pull abandoned bikes and equipment off the grid. Motorsport history is littered with tragedies that have happened in Pit Lane. And being on Pit Lane just before the start of a MotoGP race gives a real perspective of just how chaotic it is under the best of circumstances. It is really easy to understand how easily someone could get hurt.
Webb did exactly what a Race Director should do–monitor a situation and take appropriate action.
Ironically, it was the chaos that Marquez sparked that ultimately worked to his benefit. Because Webb stopped everything on safety grounds and called for a quick restart, the teams had time to work on the bikes and everyone went with slicks and dry set-ups. And the grid reformed in its original configuration as per the restart rules. “They were very lucky to get away with that,” Webb said later.
At the end of the day, the three riders who initially gambled on slicks–Brad Binder, Enea Bastiannini and Ai Ogura–weren’t happy that they didn’t get to enjoy the benefits of their decision. But Binder’s bike shut itself off. Bastiannini finished seventh, more than 12 seconds down, and Ogura was ninth, more than 16 seconds back. If Marquez or Francesco Bagnaia had to serve a ride-through penalty or switch bikes, Bastiannini or Ogura may or may not have been able to hold them off. But it is likely that Bastiannini or Ogura would have finished higher than they did. So yes, the decision to stop proceedings did harm them.
Webb says the rules will be re-assessed in the wake of Sunday’s drama. And if there are penalties to be assessed, by all means, assess them. But Webb’s snap decision meant that I’m not here today writing a story about a pit lane tragedy. That’s a win in my book.

disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML,
adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Screen-reader and keyboard navigation
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with
screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive
a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements,
alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website.
In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels;
descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups),
and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag
for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology.
To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on
as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
Disability profiles supported in our website
Epilepsy Safe Mode: this profile enables people with epilepsy to use the website safely by eliminating the risk of seizures that result from flashing or blinking animations and risky color combinations.
Visually Impaired Mode: this mode adjusts the website for the convenience of users with visual impairments such as Degrading Eyesight, Tunnel Vision, Cataract, Glaucoma, and others.
Cognitive Disability Mode: this mode provides different assistive options to help users with cognitive impairments such as Dyslexia, Autism, CVA, and others, to focus on the essential elements of the website more easily.
ADHD Friendly Mode: this mode helps users with ADHD and Neurodevelopmental disorders to read, browse, and focus on the main website elements more easily while significantly reducing distractions.
Blindness Mode: this mode configures the website to be compatible with screen-readers such as JAWS, NVDA, VoiceOver, and TalkBack. A screen-reader is software for blind users that is installed on a computer and smartphone, and websites must be compatible with it.
Keyboard Navigation Profile (Motor-Impaired): this profile enables motor-impaired persons to operate the website using the keyboard Tab, Shift+Tab, and the Enter keys. Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
Additional UI, design, and readability adjustments
Font adjustments – users, can increase and decrease its size, change its family (type), adjust the spacing, alignment, line height, and more.
Color adjustments – users can select various color contrast profiles such as light, dark, inverted, and monochrome. Additionally, users can swap color schemes of titles, texts, and backgrounds, with over seven different coloring options.
Animations – person with epilepsy can stop all running animations with the click of a button. Animations controlled by the interface include videos, GIFs, and CSS flashing transitions.
Content highlighting – users can choose to emphasize important elements such as links and titles. They can also choose to highlight focused or hovered elements only.
Audio muting – users with hearing devices may experience headaches or other issues due to automatic audio playing. This option lets users mute the entire website instantly.
Cognitive disorders – we utilize a search engine that is linked to Wikipedia and Wiktionary, allowing people with cognitive disorders to decipher meanings of phrases, initials, slang, and others.
Additional functions – we provide users the option to change cursor color and size, use a printing mode, enable a virtual keyboard, and many other functions.
Browser and assistive technology compatibility
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
