Valentino Rossi was back in the saddle today, testing his shoulder at the Italian Misano track ahead of the official MotoGP test scheduled at Sepang next month. Barred from turning a wheel on the Ducati Desmosedici GP11 because of the MotoGP winter testing ban, Rossi had to make do with a WSBK-spec 2011 Ducati Superbike 1198 SP to test his fitness levels.

Rossi’s fitness for the upcoming season is a large variable for Ducati, as the race team will need Rossi’s input at Sepang to not only further setup the GP11 for the nine-time World Champion, but his input is likely to find its way into all the Desmosedici’s on the MotoGP grid (Hector Barbera was just recently quoted as saying as much).

If his shoulder is still not up to racing levels, Rossi may not be able to fully diagnose what he needs from the GP11, setting Ducati Corse back a few steps from the rest of the competition. A statement from Rossi and a slew of hi-res photos await you after the jump.
