Cal Crutchlow's quest to end his World Superbike victory drought at Misano got off to an appropriate start as he grabbed the fastest time at the end of day one.
Identifying the circuit as a good venue to break his duck having won at Supersport level last season and tested there on the Superbike recently, Crutchlow launched himself to the top of the timesheets late on with a front-running lap of 1min 36.288s.
It was enough to deny Troy Corser a perfect day, the practice pace setter once more showing most of his rivals the way despite a mid-session tumble that threatened to hamper his progress.
Title chaser Leon Haslam completed the top three yet again to out pace new championship leader Max Biaggi, the Aprilia man improving to sixth place but emerging four tenths off his main rival.
Ducati maintained their presence with four representatives inside the top ten, Michel Fabrizio leading the way in fourth, ahead of fifth place Carlos Checa, seventh place Shane Byrne and ninth place Luca Scassa.
James Toseland completed the top ten, but he was another to lose time when he suffered a fall from his Yamaha.
Jakub Smrz, who tested for BMW during the break, rose to set the 11th fastest time on his B&G Ducati, ahead of Sylvain Guintoli, Noriyuki Haga, Tom Sykes and Ruben Xaus.
There was continued frustration for Honda though, with 2009 Misano winner Jonathan Rea down in 16th, while his team-mate Max Neukirchner could only manage 18th best, the pair 1.5secs off the front.
A slightly bruising session for some riders, Chris Vermeulen and Lorenzo Lanzi joined Corser and Toseland in coming off their bikes during the hour.
