After testing the Ducati Desmosedici GP 12, the 1000cc bike for MotoGP next year at Mugello, Valentino Rossi had declared that he was pleased with the way the bike was shaping up.  Now a couple of days later, its creator Filippo Preziosi has declared that he is pleased with the technical inputs that Rossi has been giving for the development of the GP12.  Preziosi is hoping that the GP12 will not be plagued by the front end chatter and lack of grip problem that the GP11 is currently facing.
