Championship leader Maverick Vinales topped Warm Up at the Italian Grand Prix, ahead of rookie Johann Zarco and Andrea Iannone - who found some form after having suffered with illness so far at his home race.
Loris Baz had a big crash but he is ok, and Marc Marquez had a high speed run off through the gravel - but stayed upright.
Andrea Dovizioso sat out most of the session, suffering from illness.
