Ducati Corse press release:

Troy Bayliss returns to the track on a Ducati race bike! The Australian rider, who will follow this weekend’s Superbike action at Monza from the Ducati garage, will test the Desmosedici GP9 from May 12th to 14th at the Italian circuit of Mugello, alongside the team’s official MotoGP test rider Vittoriano Guareschi. The test has been planned for a while and will be repeated during the year at future official sessions of the Test Team. Ducati can thus count on the feedback of a three times world champion, whose talent and experience will contribute to the continuous development work carried out on the Desmosedici GP9 and GP10.
