Sepang MotoGP test times - Tuesday 1pm

A damp track caused by overnight rain meant that although the track opened at 10am, all bikes remained in the pits until 11:15am.

World champion Casey Stoner is not testing today after aggravating an old back injury. The Australian is now resting and aims to return tomorrow. The four laps credited as Stoner's were by test rider Kousuke Akiyoshi.

Note that some of the times listed for Ducati riders were actually shakedown laps, on their bikes, completed by factory test rider Franco Battaini.

However, Valentino Rossi has made his debut on the all-new (and all-black) Desmosedici GP12, with which he moved to the top of the timesheets at 1pm.

All twelve manufacturer riders are present for the three-day test, plus the Forward Racing and BQR 'Claiming Rule Team' teams.
