Rain welcomed the premier class back to Misano and it led to a bit of a mid-session lull as the downpour intensified, but Johann Zarco was soon back out, demoting his Ducati colleagues and increasing his advantage with every lap. The Frenchman’s final flying lap put him almost a second and a half ahead of the closest challenger, a role taken up by Marc Marquez in the closing stages of FP1. After leading the way early on, Jack Miller dropped to third, with Jorge Martin making a late jump to fourth. Franco Morbidelli in fifth was the lead Yamaha, courtesy of a fine final lap, while Pecco Bagnaia dropped to sixth after an uncharacteristic tumble at turn 8.
The KTM trio of Miguel Oliveira, Danilo Petrucci and Iker Lecuona finished FP1 in close proximity on the timesheets, although the Spaniard was two seconds slower than the leader. Joan Mir rounded out the top 10 positions, while teammate Alex Rins ended the morning in 16th place. A grumpy Fabio Quartararo returned to his garage with 18th position on the timesheets, three seconds behind his leading compatriot and not enjoying the challenging conditions.
