With track temperature finally reaching numbers over the legal drinking age in most countries, the premier class got an opportunity to sample some hard rubber, no one more eagerly than the world champion. Marc Marquez set his flag at the top of the timesheets early on and after losing a wing in a tussle with Karel Abraham, the Spaniard soldiered on semi-wingless and went even faster. The used hard tyres eventually gave up on lap 13 in infamous turn four and while Marquez was getting back on track, Maverick Vinales swapped to some new rubber to steal the attention on the timing screens for a quarter of a second. The two Spaniards shared the first two positions and continued to look solid on race pace, although the world champion dipped into the high 1:30s a touch more. Quartararo missed out on seeing his name at the front of all practice sessions but he was close by in third, less than four tenths off the leader.
Best of the rest, Jack Miller stayed Ducati’s lead man in fourth and with pretty reasonable pace, while Alex Rins found some speed to join the top five ahead of his Q1 appearance. Joan Mir followed his teammate closely once again, while Andrea Dovizioso continued an underwhelming weekend in seventh, almost a second off the leader. Franco Morbidelli, Cal Crutchlow and Danilo Petrucci rounded out the top ten, while Valentino Rossi could not quite match his speed from FP3.
