Barbera ahead of Rossi and Hayden

Pramac Ducati's Hector Barbera outpaced the factory Ducati pair of Valentino Rossi and Nicky Hayden over a single lap to leave Sepang as the fastest GP12 rider, at the conclusion of the MotoGP shakedown in Malaysia.

Barbera, who is using the Desmosedici which Rossi rode at Valencia in the November test, completed his fastest lap in a time of 2m 01.231s to be ranked sixth fastest.

The Pramac team focused on chassis and suspension work on the 'Valencia-spec' GP12, which has since become Barbera's satellite-spec 2012 machine.

“I am very pleased with the day just passed. The feeling with my Ducati is getting better and I'm starting to understand how to use an engine that has a very different response from the 800 last year,” said Barberra.

“The behaviour of the bike is quite severe, but we still have improvements to make in anticipation of the first race. I can't be anything other than happy with the result today.”
