Ducati moved to the top of the timesheets in the second knockout Superpole session, but it is Regis Laconi who is emerging as their surprise pace setter.

By contrast, factory rider Noriyuki Haga was the highest profile casualty from the session, the Japanese rider unable to find the pace he needed with his final effort to sneak into the top eight shootout. He will start a disappointing 13th.

With three privateer riders, Laconi, Leon Haslam and Jakub Smrz, making it through, there were some surprise faces missing the cut, including both Suzukis, Yukio Kagayama and Max Neukirchner in 11th and 14th respectively, while Shane Byrne's tough weekend continues with 15th on the grid.

Elsewhere, Shinya Nakano just missed out on a top position after gambling on not venturing onto the circuit in the latter stages, the Japanese rider being joined by countryman Ryuichi Kiyonari on the third row.

Tom Sykes also missed out in 12th, while Broc Parkes was 16th and slowest for Kawasaki.

Laconi, Michel Fabrizio, Haslam, Jonathan Rea, Max Biaggi, Smrz, Ben Spies and Carlos Checa go ahead to challenge for pole position.
