MotoGP riders learned a new English word last Sunday at Buriram. Typical of this was Joan Mir, who had crashed out shortly after the halfway mark. "I have burns," he explained to journalists, before turning to the Honda HRC Castrol press officer to ask "como se dice? (how do you say that in English), before journalists jumped in with the word "blisters". "Ah, the tire also!" Mir joked.

Blisters were a common theme. Official air temperature of 36°C (measured in the shade) meant there was little respite for rider nor machine. The combination of blazing sun, 300 horsepower, and hot air meant that the heat produced by the engines was not being dissipated to the air, but heating up frames and chassis as well. Temperatures of metal parts were reaching nearly 100°C.

In many ways, the 2025 MotoGP championship promises to be one of the more interesting in recent years. Perhaps not the most closely contested - the general consensus among fans and pundits alike is that you can take your pick of whether it will be Pecco Bagnaia or Marc Márquez who ends up lifting the 2025 MotoGP crown - but behind the title fight, there are some fascinating developments to watch out for.

We may as well start with that title battle. The dominance of Ducati was so great last year that it is hard to imagine anyone other than Marc Márquez or Pecco Bagnaia walking off with the title. Despite the fact that they are sticking with their GP24 engine - a little more on that later - both Bagnaia and Márquez showed pace during the test, Márquez' race simulation at Buriram almost fast enough to win a sprint race.

The Buriram MotoGP test confirmed Ducati as the preseason favorite, with Aprilia a close second and KTM possibly on the prowl. But what about the Japanese manufacturers? After a couple of years in the wilderness, are they any closer to regaining competitiveness?

It has been quite the day at the Sepang International Circuit. The first day of the official MotoGP test at Sepang and we are already three riders down. For the second consecutive year, Raul Fernandez has crashed during testing and ruled himself out of the remainder of the test, fracturing a metacarpal bone in his left hand, as well has his little toe. Fabio Di Giannantonio had a silly crash, landing a wheelie badly at the end of the day after doing his practice starts, and breaking his left collarbone.

But the biggest news is that Jorge Martin had a massive highside at Turn 2, after completing just a dozen laps. The force of the crash was so severe that he fractured the fifth metacarpal of his right hand and the third, fourth, and fifth metatarsals of his left foot. The injury on his right hand is to the head of the metacarpal, where the bone in the hand joins the bone of the little or pinky finger. The metatarsal bones are the long bones in his foot joining his ankle to his toes.

The injury to his right hand will probably rule the reigning world champion out for the Buriram test, which takes place next week, and will leave him to ride the fully homologated 2025 Aprilia RS-GP for the first time at the opening round of MotoGP in Buriram at the start of March.

The Blame Game

It is hard to overstate just how MotoGP has changed in the last five or so years. Where once bikes were short and high, to maximize turning and pitch under braking, now they are long and low, with a focus on acceleration and power. A lot of the change has been blamed on aerodynamics, as the most visible difference between, say, 2019 and 2024.

That is certainly how factories first saw the role of aerodynamics, but that too has changed since 2019. "Some years ago, if you looked at the telemetry, you can easily understand that one of the most important problems of the bike is wheelie," Ducati Corse CEO Gigi Dall'Igna told me in an interview in 2022. "You cannot accelerate as much as you think because of the wheelie. So you have to try to understand what you have to do in order to reduce this problem. So we started to develop the wings, we started to lower the center of gravity on the bike."
