Jorge Martin's crash in the first hour of the Sepang MotoGP test has caused tension between Aprilia and the official tire supplier Michelin. Martin suffered a huge highside in the first hour of the test, when his rear tire let go in Turn 2 and flicked him over the bike. He landed very heavily, fracturing a metacarpal bone in his right hand and three metatarsal bones in his left foot.

Martin has since had surgery to fix the metatarsal with a screw, and is set to miss the final preseason test at Buriram. He hopes to be fit for the opening round of MotoGP at Buriram to be held from February 28th to March 2nd. But that means he will start the 2025 MotoGP season and attempt to defend his title with just 13 laps under his belt so far this year, and having played almost no role in developing the 2025 Aprilia RS-GP he will be riding this season.

On the Wednesday evening, Aprilia CEO Massimo Rivola came into the media center to explain to journalists what Aprilia believed had happened. Though he did not accuse Michelin directly, he left little room for any other conclusions. "It was a bad crash for no reason, with no mistake on his side and no mistake on the bike’s side," Rivola said. Nor was it a cold tire. "The tires were in the right temperature and the right pressure. But we have no explanation in fact."

Out early

It has been three long days of testing, and a lot of work, for me as a journalist as well as for the riders and the teams. Of course, I did my work from the comfort of an air-conditioned press room, which made it a fraction easier than riding a 300 horsepower motorcycle as fast as possible in temperatures of well over 30°C.

So no long and detailed analysis tonight. Plenty of time for that in the coming days. For now, here are my initial reactions to what we saw and heard at the Sepang test.

Ducati's dilemma

There can be no doubt that the Ducati Desmosedici GP24 is still an outstanding motorcycle. The three GP24s were in the top four or five on the first two days of the test, and Alex Márquez bettered Pecco Bagnaia's time from last year at the Sepang test by nearly two tenths of a second.

So can Ducati make a better motorcycle? Even Ducati aren't sure. Both Pecco Bagnaia and Marc Márquez are yet to be fully convinced that the GP25 engine is an improvement on the GP24. It has a bit more power, delivers it more smoothly, but it loses out in braking. And there is more time to be gained (or in this case, lost) in braking than in acceleration.

The factory Ducati riders spent almost all the test on the GP24 aero package, as well as the GP24 frame, while Ducati engineers tried swapping out all sorts of different parts in different configurations to try to improve the bike.

After the disaster of the first day of the Sepang MotoGP test, we got through the second day without losing another rider, reducing the rate of attrition to just 1.5 MotoGP riders out through injury a day. No doubt the massive crashes of Jorge Martin, Raul Fernandez, and Fabio Di Giannantonio had served as a useful warning of what is at stake in this preseason. But the conditions helped too.

It was a lot hotter on Thursday, and the sun drove air and track temperatures up much closer to what we would normally expect in Sepang. Yesterday's 38°C track temperatures were replaced by a much more usual 55°C. And also, nobody was much interested in using the medium rear, concentrating instead on the soft.

"I think the medium here is the same as Silverstone and Barcelona, but we struggle a lot to make it work," Fabio Quartararo told us. "The gap between the soft and the medium is too much and the drop is the same as the soft. So, I’m not using the medium any more, and I think everybody is using the soft."

A day relative free of drama - there were still more than a few crashes, including both Ducati Lenovo riders, though nothing serious - and a day on which the riders could focus on working. The heat kept a lot of riders in the garage for a couple of hours around 2pm, then a very brief rain shower chased everyone off the track again, but 15 minutes later work was underway again.
