Although drops of rain fell right before the start of the premier class session, riders left pitlane with a glimpse of sunshine and a backdrop of dark grey clouds. Luckily for everyone, the rain failed to materialise, but riders took no chances and quickly improved FP1 times in the chase for provisional top ten positions. Many of the usual contenders put their name at the top of the timing screens at some point throughout the session but Ducati power reigned once again and Pecco Bagnaia beat the competition by three tenths of a second. Fabio Quartararo was his closest challenger in the end, while the Suzukis impressed by joining the top four in the final time attack, Joan Mir four hundredths of a second faster than teammate Alex Rins.
Jack Miller forgot all about his recent surgery and climbed into the top five and again found himself in the right place at the right time to give colleague Johann Zarco a ride to pitlane once his machine started smoking in the practice start area. Marc Marquez predictably grabbed some serious screen time, the Honda man steadily climbing up the timesheets but having a pretty bumpy final run. He had to rely on the final flying lap to break into the top ten and gave his knee, elbow and shoulder a good rodeo style workout on his way to sixth position - but after 265 days off the bike he will happy enough to be less than half a second off top spot.
Maverick Vinales finished within a tenth of his compatriot and even less ahead of Zarco. Home favourite Miguel Oliveira put his name in the limelight as well but eventually dropped to ninth place, making it five manufacturers in the top ten. Takaaki Nakagami had a bittersweet afternoon, the LCR man suffering a pretty big crash into turn 1 and worryingly walked away holding his arm. After being cleared to rejoin by the medical centre, he took part in the late time attack while in obvious pain and managed to join the provisional combined top 10, demoting his teammate by a tenth of a second. Aleix Espargaro looked like he could have completed the manufacturers' full line-up in the top 10 with his Aprilia but a late crash at turn 11 dropped him to 14th position.
