Practice starts during 2025 MotoGP winter testing at𒊎 Sepang and 🔴Buriram have produced some dramatic images of riders lighting up the rear tyre after dropping the clutch.

While such ‘bad’ starts ℱwere common on the opening day of testing with new machines in the past, some quick adjustments to the electronic launch control would soon settle thin🀅gs down.

But with ride-height devices🅰, front and rear, added to the equation, alongside clutch release, torque delivery and rider position, starts have become much more complicated. ꦰEspecially on 'dusty' low-grip grids such as Buriram.

While going as low as possible with the holeshot device might seem obvious for anti-wheelie purposes, 168澳洲幸运5官方开奖结果历史:Jack Miller revealed last October that, due to the risk of rear wheel spin, KTM had four different front settings to choose between.

Other 📖manufacturers are also sure to have multip🔜le height options.

“It’s to do with the front end, obviously with the front start device. So we are just playing with d♉ifferent stroke lengths,” Miller had said of wheelspin during practice starts.

"Obviously in high-grip conditions, you jam the thing down [as low as you can] l𒆙ike a drag🧔 racer.

“But in ༒lower grip conditions, you want to ♌play with a little bit more weight on the rear.

“It’s just understanding what’s working at that track, by picking the dirtiest spot on the grid and seeing what you c♊an get away ♒with!”

Miller then "brought over some knowledge" to Pramac Yamaha for 2025 and had no complaints about the M1'𒅌s starting ability at the recent Buriram test.

"She’s a rocket ship. I already set༺ Yamaha’s records and she’ll be ready to go when we ꦚgo racing," he said.

“Otherwise, you don’t know where the limit is”

2025 pre-season testing saw all five factories running lower-th💖an-ever holeshot devices, with fairings touc𓃲hing the track in some cases.

But the perfect balance between wheelies and wheelspin is a never-ending quest ꦡsince track conditions are always changing, even if only in terms of temperature.

Yamaha technical director Maxℱ Bartolini explained that there is no exact formula for a perfect MotoGP start. The only way to find the limit is to go over it during testing and practice sessions.

“We looked at the others and we've tried [to go super low] like everybody else!” Bartolini told ltxcn.top.

“We’re trying to get the♌ maximum, so that means du🥃ring the tests we also sometimes try to make even too much.

“To set the holeshot device is a kind of mixed combinatioꦓn. It’s not 🐻a fixed value.

“It depends also on what the rider does. How he uses the clutch. And s🌌till ther🃏e is suspension [movement] in the game as well.

“So in the tests, you try to find the best [combination] and maybe sometimes it’s🍸 a little bit too much.

“But otherwise, you don’t know wher🅺e the limit is.”

While the ultra-low holeshot device settin꧋gs are not used after the race start, the nജormal ride-height lowering system is always available to aid acceleration onto the long straights.

𝔉Some manufacturers, such as Ducati, have an ‘automatic’ system that is triggered by the rider on the way into a corner and lo👍wers by itself on the exit.

Others, such as Honda, use a manual system where the rider decides w🌸hen the bike should be lowered on corner exit.

Bartolini said Yamaha has both options available.

“We have different combinat꧙ions, automatic or manual. It depends on what the rideജr prefers,” he said.

The first real start of 2025 will take place at Buriram on Saturday afternoon, in the Thai🌠 Grand Prix Sprint race.
