Alex Marquez continues to rule the testing roost in MotoGP, jumping to the head of the timesheets at the (brief) end of the morning test session at Buriram, taking over where he left off in Sepang. The Gresini Ducati rider was a quarter of a second faster than Pedro Acosta, the KTM rider closer to the front in Buriram than he had been in Sepang. Marc Marquez is currently third, despite a minor technical issue which caused him to cut one run short, while Luca Marini has put the Honda in fourth. Times are still a second off Pecco Bagnaia's pole record set in Q2 at the race last October.
Unlike Sepang, the Buriram test has a very brief test in the middle of the day for practice starts. So the track was closed to practice between 1pm and 1:15pm while the riders practiced their starts. With a lot less grip at the track, starts have been tricky, several riders either getting the bike sideways or leaving very thick black lines as they pull away.
Testing resumed shortly after 1:20pm. But there is very little track action going on in the heat of the day. The test concludes at 6pm local time, with another brief practice start session.
