Casey Stoner emerged fastest in a frenetic end to the warm-up for the British Grand Prix at Silverstone.
The lead changed hands four times on the last laps of the session, as long-time pacesetter Stoner was deposed by his Ducati team-mate Nicky Hayden, who was then beaten by polesitter Jorge Lorenzo (Yamaha), before finally Stoner returned to the front with a 2m04.711s.
Qualifying star Randy de Puniet was fourth for LCR Honda, ahead of works Honda rider Andrea Dovizioso.
The session saw two crashes at Club, the worst involving Interwetten Honda's Hiroshi Aoyama. The 250cc champion had a violent high-side as he accelerated. Aoyama landed heavily and had to be taken from the scene by stretcher.
Dani Pedrosa also crashed at the same location, losing the front end of his Honda on the way into the corner. But despite having had a massive crash at the end of qualifying yesterday, he showed no ill effects and was able to walk away immediately.
