Championship leader heads them up again
Only just behind was Jakub Smrz (Effenbert-Liberty Ducati), deposed by Checa with no time left to go faster. Yamaha World Superbike team-mate Marco Melandri and Eugene Laverty completed the front row, mastering the damp conditions well when it counted most.
The second row is headed by Sylvain Guintoli, Smrz's team-mate, with the top official BMW rider on show Troy Corser going sixth. Late faller in Superpole 3, Max Biaggi, was seventh for Aprilia and impressive BMW Motorrad Italia Superbike rider Ayrton Badovini was eighth.
