Don’t they all use pneumatic valves now? Ducati being the exception.
2025 Silly Season

Yes all the others use a gas spring instead of a steel spring, but it has the same faults.
I did know that including the Mercedes angle but back in Casey Stoner’s day when I first took an interest in the desmo thing, although I have always l loved Ducatis, I understood the maintenance of the desmo valve engines on road bikes was problematic. I don’t know whether this is still the case with Ducati more recently being a shiny appendage of VW Audi rather than the artisanal operation it once was, particularly true of Ducati Corse back then.

Again I am a technical ignoramus but the pneumatic valves still consume power as I understand or misunderstand it, which desmo valves don’t, working mechanically. Back in 2007 when Casey Stoner had the unfair bike that rode itself the Ducatis could actually rev higher than the other bikes which had spring valves, which was when the others went to pneumatic valves, Ysmaha before the end of the 2007 season as I recall with Rossi pushing hard for same; he had an engine explode or catch on fire in one of the early races with the pneumatic valve engine.

That’s the thing, getting the bike to turn was what made the difference, before Gigi it was said the L4 configuration was an insuperable problem, but Gigi fixed the handling. I am an admirer of both Ducati and Gigi but like you can’t approve the fix bring by ride height and aero trickery.

He’s no longer represented by the VR46 academy, but he still maintains good relationships with them and trains with them at times as well.
I don't wanna have to imagine a world where Pirro doesn't run at least one MotoGP race a year.
Fair point, but Bulega has been keeping Toprak honest and that’s not the easiest thing in the world.
He hasn't pushed him too hard during the weekends after Toprak learned how to ride the beemer.
Guess it is a good consolation prize for finishing second.
Last weekend’s sprint finish was MAD though!

Makes sense to miss those last 2 races as its not good to miss the preseason testing which will be on a bike 2 years newer than his current rideDiGiannantonio will undergo Surgery on his shoulder after the Thai GP and miss Sepang and Valencia.

Respectfully - that's absolutely true. However, that doesn't in any way justify the way the Chinese government treats everyone they feel obliged to subjugate. As a matter of perspective the war crimes perpetrated by the Japanese, are just a drop in the bucket compared to the 20 million who were executed, died of starvation or driven to suicide in Mao's Cultural Revolution.
No disrespect to the Chinese people but .... the CCP
If Bulega does ride as replacement are we safe to assume Toprak would finish 30 secs ahead of any finish Bulega manages hmmm ?
Possibly, but a MotoGP bike is the antithesis of everything that makes Toprak, Toprak.If Bulega does ride as replacement are we safe to assume Toprak would finish 30 secs ahead of any finish Bulega manages hmmm ?
He likes front bias, squishy tyres he can punish and a flexy chassis. MotoGP bikes do exactly the opposite of all that.

These machines are nothing like the 2019 bikes when he last competed in MotoGP.
I like Iannone and loved to see his comeback victory at Aragon would Bulega and Petrucci would deserve this ride more imo.
