Fabio Quartararo has topped the second session of free practice for the MotoGP class in Buriram, the Petronas Yamaha rider continuing his run of fastest times at almost every circuit. Quartararo won the final shootout on Friday afternoon to go nearly two tenths of a second quicker than anyone else.
Quartararo led a very strong showing by Yamaha. Maverick Viñales took second on the factory Monster Energy Yamaha machine, just ahead of Quartararo's Petronas teammate Franco Morbidelli. Valentino Rossi ended the session in fifth, the factory Yamaha rider just a few hundredths slower than Jack Miller on the Pramac Ducati, the Australian the only rider to prevent a Yamaha clean sweep.
Marc Márquez ended the session as sixth quickest, in a remarkable display of resilience. The Repsol Honda rider bounced back from a massive crash in FP1, from which he was lucky to escape with just bruising to leg, buttock, and the muscles in his back, to immediately set an impressive time on his third lap out of the box. As is his wont on Friday, Márquez did not use a new tire to chase a fast time, preferring to concentrate on race pace instead.
Aleix Espargaro posted an impressive lap to grab seventh on the Aprilia RS-GP, finishing just ahead of Andrea Dovizioso on the Ducati. Dovizioso's position belies his pace, the Italian running a close second behind Marc Márquez on race pace, just ahead of the Yamaha armada. Dovizioso's time suggests that he is not finding it as easy as he would like to set a single fast lap on the GP19 in Buriram.
The two Suzukis round out the top ten, Joan Mir ending the session ahead of teammate Alex Rins. As everyone improved their time in FP2, the top ten have provisionally made it through to Q2, which could be important if it rains on Saturday, as predicted.
