Stoner quickest in Valencia test

The Ducati rider's best effort was a tenth of a second quicker than his fastest lap in Sunday's race, while Dani Pedrosa and Valentino Rossi set the next quickest times in a repeat of the top three from the weekend's Grand Prix. Although Rossi only joined in for the last two hours of the day.

The Suzuki's of Chris Vermeulen and Loris Capirossi were fourth and fifth quickest, ahead of Alex de Angelis on the Gresini Honda and Jorge Lorenzo's factory Yamaha.

But the spotlight today was on the riders having their first tests for new teams. Several riders switched to their new homes today as Nicky Hayden moved to Ducati, Andrea Dovizioso took his place at Repsol Honda, Marco Melandri switched to Kawasaki, and Toni Elias moved back to Gresini Honda..

Other riders also joined the series today, with Sete Gibernau making his MotoGP return on the Onde Ducati, 250cc graduates Mika Kallio and Yuki Takahashi in action for Alice Ducati and JiR Team Scot Honda, and Niccolo Canepa alongside Kallio at Alice.

Dovizioso was quickest of those to change bikes since Sunday's race, setting the eighth fastest time 1.2 seconds adrift of Stoner's benchmark.

Melandri was inside the top ten and just 0.022s slower than new Kawasaki teammate John Hopkins, while Hayden was 12th for Ducati and 1.5s behind Stoner as he concentrated on acclimatising himself with the new machine.

Lorenzo continued his troubled time at Valencia with a crash during the afternoon, but was unhurt.

The test was also the first run on Bridgestone tyres for all the riders that raced with Michelin this year, on MotoGP's first day as a single-tyre championship. The test will conclude tomorrow.
