Practice starts during 2025 MotoGP winter testing a🎉t Se🌟pang and Buriram have produced some dramatic images of riders lighting up the rear tyre after dropping the clutch.

While such ‘bad’ starts were common on the opening day o🐼f testing with new machines in the past, some quick adjustments to the electronic launch control would soon settle things do꧒wn.

But with ride-height devices, front and rear, added to the equation, alongside clutch release, torque delivery and rider position, ꦑstarts have become much more complicated. Especially 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 ღalso sure to have multiple height options.

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

"Obviously in high-grip conditions, you j🧜am the thing down [aꦉs low as you can] like 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 can get away with!”

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

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

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

2025 🐟pre-season testing saw all five factories running low𝔍er-than-ever holeshot devices, with fairings touching the track in some cases.

But the perfect balance be﷽tween wheelies and wheelspin is a never-ending quest since tr🍸ack conditions are always changing, even if only in terms of temperature.

Yamaha technical director Max 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 mahbx.com.

“We’re trying to get the maximum, so that means during the tests we also sometimes try to 🍒make even too much.

“To set the holeshot device is a kind of mixed combination.𒀰 It’s not a♒ fixed value.

“It depends also on what the rider does. How he uses the clutc💮h. And still there is suspension [movement] in the game as wel🍒l.

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

“But otherwise, you don’t know where the limitꦅ is.”

While the ultra-low holeshot device settings are not used after the race start, the normal ride-height lo🍌wering system is always available to aid acceleration onto the long straights.

Some manufactur🐼ers, such as Ducati, have an ‘automatic’ system that is triggered by the rider on the way into a corner and lowers by itself on the exit.

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

Bartolini said Yamaha has both options available.

“We have different combinations, automatic or manual. It de꧟pends on what the rider pওrefers,” he said.

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