Althea Ducati rider Carlos Checa moved to within a whisker of securing his first World Superbike championship with victory in race two at Imola after Jonathan Rea suffered a mechanical problem while leading the race.
Checa leads championship rival Marco Melandri by 97 points going into the final two rounds, as Melandri finished sixth, despite running off track.
Rea again dominated the race, moving to the front right from the start. Rea was leading by three seconds from Checa with five laps to go when he slowed and let Checa passed. Rea looked to then pick up the pace, but it was clear there was a problem with his Castrol Honda Fireblade, forcing the Irishman to retire.
PATA Aprilia rider Noriyuki Haga took second place again after a poor start. Factory Aprilia rider Leon Camier took the final step on the podium - a great result for the Brit after he struggled in race one, finishing 15th.
Eugene Laverty and Leon Haslam made it three Brits in the top five, finishing fourth and fifth respevtively.
