There is an entirely unsubstantiated rumor, which I have personally decided to believe regardless of the evidence, that Dorna CEO Carmelo Ezpeleta worked hard to prevent Ducati from signing Marc Márquez to the factory team. After two sprints and a GP, you have to concede that he would have been right to try to interfere. So far, Márquez has looked pretty much unstoppable. Exactly as you would expect when you put the best rider on the best bike.

At the end of every Friday practice, the riders like to remind us that it is only Friday, and we shouldn't read too much into the times. Fat chance, of course, but they have a point. But "it's only Friday" takes on extra potency at the Termas de Rio Hondo circuit, given the changing nature of the track. Especially after it rained heavily overnight, and the track started the day wet and took a long time to dry out. High humidity and low temperatures add another layer of complexity, just to liven things up.

The track started off cleaner than expected. "Yesterday when I made the track walk, I thought that the track was more dirty," Marco Bezzecchi said at the end of the first day. "But when I rode the bike this morning, to be honest it was much much better compared to the past times we came here."

The track may have started from a better base, but the grip levels were still changing on pretty much every exit as more and more rubber got laid down. That makes working out where riders stand relatively complicated, though we can take a stab at it by looking at the timesheets.

The vagaries of politics meant that MotoGP missed out on going to the Termas de Rio Hondo in Argentina in 2024, and the vagaries of politics mean we are going back again in 2025. Probably for the very last time, as next year there will be a race in Brazil, at Goiania, and possibly another near Buenos Aires, where Dorna Chief Sporting Officer Carlos Ezpeleta visited in February.

The vagaries of politics are why Termas de Rio Hondo was built and then upgraded to host MotoGP in the first place, the regional government hoping to attract tourism and economic activity to a relatively remote part of Argentina. That makes it one of the longest and most tiring journeys for everyone in the MotoGP paddock, and also one of the most expensive. And given the diminishing returns from all forms of journalism, it means there are fewer reporters on the ground than there are working class people on an F1 grid.

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.

In any other season, the MotoGP engine homologation rules are relatively straightforward. Or as straightforward as they can be when engines are sealed and set for a single season, with concessions for underperforming manufacturers.

But the imminent change of technical regulations for the 2027 season has added another layer of complexity. To reduce costs, and prevent factories from having to develop an engine for the 2026 season, as well as a completely new 850cc engine with a maximum bore of 75mm, engine development is also frozen for the 2026 season.

What this means in practice is that the engine design manufacturers in Concessions Categories A, B, and C (Ducati, KTM, and Aprilia) present for homologation before the opening grand prix of the 2025 season at Buriram in Thailand will have to remain unchanged for the 2025 and 2026 seasons.

Trust the process

That sounds simple, but there is a little more to it than that. So I have set out the process below.

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?

The final preseason test is a strange creature. Most of the work has already been done at the first test at Sepang. Parts have been tried, and either accepted for use or sent back for scrap. (The parts may be scrapped, but the ideas will be laid aside and the results used to make something better next time.) So there really is a lot less for the teams and factories to test.

Looking at pictures from Buriram, you would be hard pressed to see any new parts compared to the bikes used at Sepang. Or indeed new parts compared to the Barcelona test. As I wrote after Sepang, we are at the stage of MotoGP bike development where designs are converging on the most efficient aerodynamic shape. And we probably won't see any major changes until the new technical rules arrive in 2027.

The MotoGP regulations allow for the teams and factories to have two official tests before the start of the season. The first is traditionally at Sepang, the second at the track where the opening round of the season is set to take place.

In theory, 2025 follows the same pattern. In practice, the second MotoGP test of the 2025 preseason is more of an extension of the first test than a completely separate entity. Since the riders packed up on Friday night, they have traveled to Thailand, had a day of rehearsing the MotoGP launch on Saturday, attended the huge official series launch in the center of the Thai capital Bangkok, a day off on Monday (though likely filled with sponsor obligations in an important market, especially for factory riders) and then a day to discuss the outcome of the Sepang test and the plan for the Buriram test on Tuesday, before taking to the Chang International Circuit for two days of testing on Wednesday and Thursday.
