Valentino Rossi bounced back from his title defeat by putting the new 800cc Yamaha on top of the post-season testing timesheets, at Valencia on Wednesday.

The Italian, who lost out on a sixth consecutive premier-class crown with his fifth lap fall in Sunday's season-ending grand prix, not only put the 2007 Yamaha at the head of the field - but also beat the best 990cc race lap, set by Ductai's Loris Capirossi, by 0.224secs!

That pace was enough to keep Rossi just 0.03secs clear of Fortuna Honda's Toni Elias, riding a 990cc RC211V, who made an impressive start to his new Bridgestone career by lapping 0.9secs faster than he had on Michelins during the grand prix - with team-mate Marco Melandri a fraction slower for third at the end of day one.

Fourth fastest was again Rossi, this time on his 2006-spec 990cc machine, but Capirossi was just 0.01secs slower on the new 800cc Ducati. The Marlboro rider was 0.41secs slower than The Doctor's 800cc pace and just 0.03secs ahead of Rizla Suzuki's John Hopkins, who completed the top six.

Hopkins and seventh fastest team-mate Chris Vermeulen were riding with an 800cc engine in their 'old' 990cc chassis and so were delighted to have lapped comfortably inside their best 990cc race times after their first ever day on an 800.

Eighth fastest was the first of the Honda 800cc riders, Dani Pedrosa, who first rode the RC212V at Motegi, while the Spaniard's 2006 rookie of the year rival, Casey Stoner, was only 0.2secs behind on his factory Ducati, Bridgestone and 800cc debut.

Alex Barros completed the top ten on his MotoGP return, after almost a year's absence - the 2006 WSBK race winner riding a 990cc d'Antin Ducati on Bridgestone tyres and lapping almost 1.5secs inside the best d'Antin lap, on Dunlop tyres, in Sunday's GP.

New world champion Nicky Hayden was eleventh fastest, but still within one second of Rossi, on his Honda 800cc debut - while Ilmor gave Jeremy McWilliams and Andrew Pitt a test on its X3 as the new team evaluates possible riders for next season.

McWilliams was the fastest of the pair, lapping 0.8secs quicker than WSBK front runner Pitt, and the experienced Ulsterman turned heads by beating Garry McCoy's best race lap from the grand prix.

OK, Valencia is quite a tight track. But it's still amazing, that the new 800cc bikes are FASTER than the 990cc bikes.
The Illmor 3secs behind. Well, they need to improve a bit over winter.

from what i've been told, the 990s were tuned back a bit for fuel consumption reasons (at least honda's were). i think with the smaller engine thay are able to get similar or better performance without the fuel consumption issues. just what i've heard :O

Valencia is a small track, 800 bikes probably carry more cornering speed.

just wait until they do the Sepang test, or go to take like Motegi and Mugello that requires horsepower.

but the time is still very impressive. Rossi is still the best

The 800's will have 1 litre smaller tanks for next year that will cut performance
more than anything else

Quite simple - most of the 990's were tamed down to make the [power delivery useful - Honda were reputed to be able to get 250 - 275bhp out of the 990 :dowhat it just couldn't be put onto the tarmac ...... with the smaller engines the way it develops it's power (higher up the rev range, away from peak torque) means it can be used harder plus the bikes are (a little) smaller and lighter.... just like why a well sorted 600 can pace with a litre bike on the right circuit :O There were a couple of circuits in the old 500 stinker days where the 250's ran the same times as the 500's ........
