Eugene Laverty stole provisional pole from Chaz Davies at the chequered flag with Tom Sykes in provisional third place. Marco Melandri was the last rider under 1'59, and the only rider in the top ten not to improve on his morning's time.
Leon Camier crashed, causing the session to be red-flagged, and was taken to the medical centre, but he still managed to go sixth fastest, with over thirty minutes remaining.
Carlos Checa struggled as the Ducati Panigales suffered from a twenty kilometre per hour speed difference between them and the Aprilias on the long straight. Ducati riders have to salvage as many points as possible before returning to tracks more likely to favour their bikes, and Mark Aitchison's Effenbert Ducati, the only one of the older 1098Rs racing, was well over 30kmh slower, never even passing the 300kmh mark.
