11:43 - Acosta is joined by Pecco in the 1:29 club, and it's the Italian who now sits quickest in the early stages of Day 1 here in Thailand. 0.024s is the gap between the Ducati and KTM riders.
11:33 - A change at the top. Pedro Acosta (Red Bull KTM Factory Racing) is the first to have a gander into the 1:29s. The #37 is now 0.199s clear at the summit thanks to a 1:29.952.
11:00 - First hour in the books. Marco Bezzecchi (Aprilia Racing) sits P3, 0.258s away from MM93, with Luca Marini (Honda HRC Castrol) and Alex Marquez (BK8 Gresini Racing MotoGP) rounding out the top five. And a little further down in P8, it's a welcome return to action for 2024 World Champion Jorge Martin (Aprilia Racing) - good to see the #89 back.
10:50 - Gravel trap to P1 for the champ. Marquez lands a 1:30.151 to go top just before 11 am local time, with teammate Francesco Bagnaia 0.121s in P2 so far.
10:20 - Not an ideal start for the World Champion. Marc Marquez lost the front early at the final corner to endure a crash within the first half an hour of the test, and while the bike looked pretty second hand, thankfully the #93 is uninjured.
10:05 - Here we go then, the Buriram Test is alive and kicking, with Alex Rins (Monster Energy Yamaha MotoGP) winning the race to be first out of pit lane.
09:45 - Good morning MotoGP fans! Hope you're well and ready for bikes to be on track again. It's great to be back in Buriram as we get set for two crucial days of scorching (literally) test action at the Chang International Circuit, with the track going green very shortly.
