Maverick Viñales topped the second session of the day at Assen for the MotoGP class, adding the fastest time in the afternoon to his fastest time of the morning. Though a few riders improved their time in the first half of the session, rain - light at first, and then a proper downpour - ruined most riders' attempts to go faster, with the provisional top 10 remained unchanged from the morning.
In FP2 proper, Miguel Oliveira ended up in second, Fabio Quartararo was third, Marc Marquez was fourth, and Joan Mir was fifth quickest. But the biggest news of the session was the massive highside for Marc Marquez at Duikersloot, at the southernmost part of the circuit. The Repsol Honda rider had the rear of the bike come round on him, and was flung high into the air, coming down heavily. Marquez could get up and walk away, and ride back to the pits on the back of a marshal's machine. Marquez did not go back out in the rain. But he should be fit to ride again in the morning.
