Dani Pedrosa will head into this afternoon's Czech Republic Grand Prix having been fastest in all dry sessions - including a sizable 0.699sec advantage in Sunday morning warm-up.

Yamaha's reigning world champion Jorge Lorenzo got closest to Pedrosa with team-mate Ben Spies 0.853sec from the top in third. Spies and fourth place Marco Simoncelli (Gresini Honda) both improved one place their qualifying positions - at the expense of Casey Stoner.

The world championship leader, who topped the wet Saturday morning session, looked visibly unhappy on his way to fifth (+0.909sec). The Australian has been struggling with feel and chatter on his Repsol Honda this weekend.

Team-mate Andrea Dovizioso took sixth (+1.128sec) with lone remaining Suzuki rider Alvaro Bautista making great gains compared with his 14th in qualifying to claim seventh this morning (+1.246sec).

Rookie Cal Crutchlow was the top satellite bike rider in eight (+1.599sec) for Monster Yamaha Tech 3, with Nicky Hayden the leading Ducati in ninth (+1.687sec).

A season best sixth in qualifying, Hayden's team-mate Valentino Rossi dropped back to eleventh this morning (+1.768sec).
