The World Supersport race was halted after four laps after the front four riders all went down on oil that was not spotted from a third lap crash at Variante Della Roggia. The restart lasted for two laps before a rider crashed out of the Ascari chicane, immolating the motorbike and destroying the ablative air fencing; an automatic red flag. On the third start of the race, a ten-lap dash, a rider ploughed through Prima Variente, the first chicane, taking a few other racers with him. A third red flag was waved and the race was postponed until after the second World Superbike race. Nobody was significantly hurt in any of the incidents.
