After an optimistic debut test on the all-new Desmosedici GP12, Valentino Rossi's 2012 MotoGP hopes took a serious knock at this week's Sepang return.
Fifth fastest and 1.22sec from Honda's Casey Stoner after the first test, Rossi dropped to tenth place during the final pre-season Malaysian trip.
The only positive was that the gap to Stoner - again fastest - was cut to 1.07sec, but that was of little consolation to the seven-time MotoGP champion, preparing to start his second season at Ducati.
“It has been quite negative,” said Rossi, talking in the Sepang paddock as storm clouds gathered overhead. “The only positive is that the distance to first place is a bit less, but unfortunately our position is a lot worse.
“Being just behind the factory Hondas and Yamahas after the first test was positive, but everything we tried here - especially to fix our biggest problems - didn't work.
“We are closer to the top, but now we also have the Monster Yamahas and satellite Hondas in front of us. We are very worried for this reason especially.
“The new electronics worked well, and helped in the straight, but I'm too slow on corner entry and not able to keep the right corner speed. I also have some movement in acceleration.
“We are not very, very far - but 0.6sec in the pace is quite a lot.”
Rossi explained that his biggest difficulty is understeer, which forces him to use the brakes too much, sapping his corner speed.
But Rossi maintains the GP12, which features Ducati's first aluminium twin-spar frame, is still an improvement over last year's troubled carbon fibre then part-aluminium 800cc machine, with which he took just one podium finish.
