The flexibility of Red Bull KTM’s MotoGP™ ‘rubber man’

KTM have the fastest Grand Prix motorcycle in the world, but performance and results depend on prime use of MotoGP’s spec-Michelin race rubber. Who is responsible (and how) for giving the KTM RC16 its powerful black ‘boots’?

If you are ever lucky enough to enter the Red Bull KTM Factory Racing MotoGP pitbox then there’s a good chance the first person you’ll see is a tall, strapping Brit called Craig Burton. ‘Burty’ will be partially hidden by racks of tires, most of them wrapped in their warmers with blinking lights, and he’ll be obscured by boxes, work desks, tools and other storage. In some of the smaller, more antiquated circuit pitlane facilities he’ll be like a rabbit in a warren, tucked behind the row of KTM’s electronic technicians and then the walls of the main work area where the four KTM RC16 motorcycles are being feted and prepped by the rest of the crew. Burton will hustle into view when the 12kg wheel-and-tire combos needs to be shifted and slotted onto the race bikes. He is back and forth for most of the day, white gloves covered in dark dust. “It’s a job that nobody wants to do, a lot of the time,” the 48-year-old laughs. Why? “It’s a little thankless at times. You’re the guy stuck out the back and you’re also on your own and have to fix issues by yourself. You are multitasking all the time.”

Brad Binder and his Team PC: Rob Gray

Burton has been responsible for Brad Binder’s tires and brakes since the South African came into the team in 2020. Before that, he readied the material for Pol Espargaro from 2018. He is a veteran of world championship racing since 2003 and has a diverse education in the confines of a pitbox. “I’ve done all sorts: mechanic, head mechanic, a bit of gearbox stuff, spare parts. A bit of everything, master of nothing,” he chuckles, the large physical presence contains a warm and agreeable nature.

MotoGP moves with the Michelins. Whether it’s the amazing grip (lap records fall every season), anticipating the ‘drop’ (the phase where the three compound choices start to lose optimum performance in a race) or the changing front pressures partially caused by the demands of bike aerodynamics and braking power; tires are the talk. Therefore, despite how he modestly downplays his role, Burton also knows his importance to Binder and the race effort is as the same as anybody else’s.

“The biggest thing is assisting the Crew Chief and trying to take pressure off him,” he explains. “We can only use 10 front tires and 12 rears during the GP weekend so it’s about managing and documenting. You might only use a tire for a few laps and then use it again the next day. I also manage the heating time for the slicks because if you heat them too much or pre-heat them for the next day then the performance is significantly less. In recent years the job has become much more computer-orientated; looking at data, check pressures and temperatures and provide an overview for the rest of the guys. I even have scope to make a decision on a tire choice if there is no time during practice.”

“We have front slicks, rear slicks and Wets and I also manage the brakes: we have six sets and five-six sets of calipers in rotation. Ten front rims and twelve rear rims and then five sets for the Wets. You have to be organized or you’ll be massively in trouble! You have to be ‘on it’. I was very experienced when I came to the team but it still took me eight-ten months to figure out the job in the first year. And it has evolved; the planning and the heating system and the scheduling.”

Burty might keep company with cooking rubber and smoldering carbon discs for most of the time in the pitbox but that only increases the need for efficient autonomy. “I have to be very proactive because I’d waste an hour a day running around asking questions otherwise,” he says. “The Crew Chief will decide the race tire pressures, that’s his responsibility. I can give an opinion…because sometimes the engineers get so focused on the data on the screen in front of them whereas I can give an overview, even down to things like last minute weather checks and basic gut instinct!”

Changeable weather across a three-day MotoGP Grand Prix provides the ultimate head-scratcher for teams and riders. They basically have 45 minutes with Free Practice 1 on Friday morning to dial-in a circuit (and the feeling and condition of the asphalt) before every lap counts in afternoon Practice. Riders are quickly into the heat of Q1 and Q2 on Saturday morning and then the afternoon Sprint. Add the climate, and the upheaval of a 22-race championship with eight overseas events and there is a lot to predict and plan.

“Wet and dry conditions are the worst,” Burty bristles. “Many times you prepare the Wets and then just forget about them but when it’s inclement or changeable then it gets hectic. You have to be organized with your brakes as well. Every GP is like a ‘reset’ with the material because you cannot be sure that disc/pad combination that worked last time will go straight into the bike and work the same again because they are freighted around the world.”

“There is a 30-page Brembo manual to follow with the ‘maximums’ and ‘minimums’ and pad thickness,” he adds. “Some riders are very different in how they brake. Brad, for example, creates a bit more temperature than Pedro [Acosta]. So, we have to watch it. Sometimes we might have a different disc option for diameter or cooling capacity that we can jump to. With the wheels I’ll have high mileage rims, medium and low. You need a system to rotate them and I will put the older stuff on a Friday, medium for Saturday with a good set for the Sprint and then think about the best combination for the race.”

Burton is constantly shuttling to the Michelin work area in the paddock. “It can be 22-23,000 steps a day,” he says. He also has to pull and roll all the weight around: “there is a bit of physicality to it.” Then there’s the occasional inconvenience of having to bundle wheels and tires through the box and thread through groups of guests or VIPs. “I try to be fairly civil. I probably come across as quite intimidating but I’m not really.”

Like most people in MotoGP he feels the drain of the calendar and the demands of travelling. “But it’s OK when you get here,” he says, while talking in the Circuit of the Americas paddock for the USGP. “You have your home life and your work life. Two different families, two different worlds. The team is really important. Everybody offers a huge amount. The mechanics have a huge workload now, and that’s without any problems. I have full respect for them.”

When Binder does have the occasional departure from the KTM RC16 on track then Burty has his own evaluation to make for the crashed motorcycle. “If you are not sure about a rim or brakes then quarantine them until the next race,” he states. “It’s mostly common sense through checking: that the rims are running ‘true’, that there are no big chunks missing from the discs and there is no movement because the rider will feel it. You always have a back-up. You need to run three sets of brakes on Friday to at least have three sets ready for Saturday.”

Craig says he’s had some heart-raising moments. “One time, restarting my computer just before qualifying didn’t go down too well. I had to go analog, old-school and work through a table. The big thing is not to panic. Work the problem and prioritize because things can snowball in this job, you might get a bit behind and it messes up the preparation. For the race I need to get the tires on the bike and then the race tires covered up and to the grid with the discs because there is not much time for any change.” But he also knows when he’s made his contribution. “Second-guessing the Crew Chief…and being aware of things: their plan, what’s happening, the weather and the organization,” he confides.

Part of that methodology means that Burty will often be busy during the race itself. “I’m not a guy who sits and watches. I’ll always be doing something. I’ll have it on the computer…but I’ll clean wheels or be measuring and logging brakes that probably won’t be used until the following time.”

Black hands and sometimes a smudged face: Burton might not be fixing aero or assembling an engine but he’s just as ‘mechanic’ as any of Binder’s tightknit gang. “I’m a dirt magnet. Always have been!” he grins. “The wheels get dirty from the brake dust, especially the front, and the brakes have to be cleaned and measured…you just get black from the carbon!”

TOM VIALLE AND RED BULL KTM CHARGE TO IRONMAN PRO MOTOCROSS PODIUM

View Profile
Red Bull KTM Factory Racing’s Tom Vialle returned to the 250MX podium in Round 9 of the 2025 Pro Motocross Championship at the Ironman National on Saturday, producing a measured 3-3 moto scorecard for third overall in Indiana. In addition, defending premier class champion Chase Sexton starred with the opening 450MX moto victory of the weekend. Two-time MX2 World Champion Vialle returned to racing at Ironman's ninth round of the season after sitting out the Washougal National, powering to fifth in 250MX qualifying before racing to a well-earned third-place finish in Moto 1. Another consistent P3 performance in Moto 2 onboard his KTM 250 SX-F FACTORY EDITION earned the number 16 third overall for the day, marking a strong foundation to build from for the remaining rounds of the season. He's currently ranked fifth in the point-standings. Tom Vialle: “I had fun all day and it was nice to be back at the track after some time off. I’ve always liked the Ironman circuit and have done well here in the past, but it was really gnarly today. The woods section was slippery, and other parts were a bit sketchy, but I’m happy with my day and am looking to finish the Pro Motocross season strong.” Also back on track after a stint on the sidelines was fellow 250MX class contender Julien Beaumer, who set the eighth-fastest qualifying time, before racing to a 15th-place finish in Moto 1. Again pushing hard in race two, Beaumer finished in 13th position and was credited P14 for the weekend. Julien Beaumer: “I had a solid qualifying in P8, showed some pace there, but the beginning of each moto I was just a little stale, I would say – just a bit slow at the start. I ran my best laps later in the motos, but I’m happy to get through the round and log consistent laps. I think we’re on a path forward now, so I’m excited to get back to work this week, and be stronger again at Unadilla.” In the 450MX division, previous round winner Sexton – equipped with the KTM 450 SX-F FACTORY EDITION – posted the third-fastest time during 450MX qualifying, enjoying the fast, flowing Indiana race track on what was a clear day. For Moto 1, Sexton launched to a strong start, only to experience a fall during the opening stages of the race. In what was an inspired performance, the 25-year-old put in a convincing charge through the pack, ultimately delivering a remarkable victory to open his account for the weekend. Another solid start to Moto 2 saw Sexton chasing down the overall win, briefly entering third position before a fall directly after the finish-line unfortunately drew a premature end to his day. He was credited 10th overall due to his points scored in the opening race. Ian Harrison, Red Bull KTM Factory Racing Team Manager: "Our day started well with Tom finishing third after taking Washougal off, and in Moto 2, he rode really well to stay in contact with the leaders for the first eight laps, and third overall was a nice comeback for him. Julien didn't have a great day, but he did get through the day, and he was definitely stronger than when he left off, so hopefully he can build on this. Chase rode an incredible first moto that was nice to watch as a fan – just amazing – and he managed to ride a very calculated race to take the win. Second race, he lost control over the jump – I did not see it exactly – but afterwards I could see that he couldn't get going as the front brake was jammed on. It was unclear at that time when it'd happened, but judging from when we got to the bike, it looks to be that the brake packed full of mud, and that was the after-effect of the crash. Leading up to the crash, we're still unclear of exactly what happened, but it does look like we could be dealing with debris in the brakes from the track, and if thats the case, we need to come up with a solution on how to prevent this in the future."

AARON PLESSINGER TO MISS FINAL THREE ROUNDS OF PRO MOTOCROSS SEASON

View Profile
Red Bull KTM Factory Racing’s Aaron Plessinger will unfortunately remain on the sidelines through the final three rounds of the 2025 AMA Pro Motocross Championship while prioritizing his health and fitness. Ongoing health issues had affected the 29-year-old prior to missing Round 8 at Washougal, however, despite initial plans to return for Ironman Raceway this Saturday, Plessinger has been recommended by his doctors to take additional time off the bike in order to focus on his recovery. A competitive start to the outdoor season saw ‘The Cowboy’ stand on the 450MX podium overall at both the Hangtown and Thunder Valley Nationals, but he had been battling illness since symptoms initially emerged at RedBud last month. Plessinger still currently sits fourth in the SuperMotocross World Championship (SMX) standings, now targeting a return in the post-season for Playoff 1 at zMAX Dragway in Concord, North Carolina, on September 6. Aaron Plessinger: "Unfortunately, getting to the bottom of my health issues is taking longer than I had hoped. My Cortisol levels are still really low and not back to where I was hoping they would be by now, so under my doctor's advice I’m going to sit out the remainder of the MX series. It’s frustrating given I was riding the best I have ridden in my career this season, but going from leading motos to DNFs is not healthy for me and I don’t think it’s what the fans or my team deserve either. I’m getting older and it’s just time for me to do some deep-diving into my health and get to the bottom of it. I’m not the first guy to go through it, so I have received a lot of positive feedback and support from my peers, and I will figure this out – it’s just something that is taking a bit longer than I had hoped. I’m already missing seeing the fans and my team every weekend, so you better believe I will be back real soon!" While Plessinger remains sidelined, Red Bull KTM Factory Racing will welcome back 250MX teammates Tom Vialle and Julien Beaumer alongside reigning 450MX Champion Chase Sexton this weekend at Round 9 of the Pro Motocross season.
