MotoGP title challenger Dani Pedrosa wasn't prepared to take any risks in the damp at Misano today as he left his Repsol Honda RC213V parked in the team garage.

Pedrosa, who won a thrilling final lap tussle with Yamaha's Jorge Lorenzo at Brno in the Czech Republic to keep the pressure on in the race for the coveted world crown, plans to start afresh tomorrow as he bids to reduce the deficit further to Lorenzo at the top of the standings in Sunday's San Marino Grand Prix.

"On days like this it's almost impossible to get any feedback on the bike," said Pedrosa.

"Actually, we saw in both sessions that the weather was changing so quickly that the riders going out with slick tyres had to come back in because it started raining or the other way around: going out with wets and destroying them in just a few laps as it was drying up again.

"The weather forecast looks better for tomorrow and Sunday, so let's hope we can take advantage of tomorrow morning's session to find a good setting and have a good qualifying."

Pedrosa's Repsol Honda team-mate, Jonathan Rea, ended the day sixth fastest as he made the most of the opportunity to familiarise himself further with the factory machine prior to his MotoGP race debut at Misano, where he is standing in for the injured Casey Stoner.
