Troy Bayliss completed his first day of testing on board the Ducati Desmosedici GP9 at Mugello on Tuesday, alongside regular factory test rider Vittoriano Guareschi.
It marked the first time the reigning triple World Superbike champion had ridden a grand prix machine since the final round of 2006 at Valencia, when he took a shock first (and last) MotoGP win during a one-off ride to replace the injured Sete Gibernau.
Tuesday also marked the first time Bayliss had experienced an 800cc MotoGP bike and was his first two-wheeled track action since concluding his motorcycle racing career with a double race victory at the 2008 Portimao WSBK season finale.
"This is literally the first time I've ridden a motorcycle since we unveiled the 1198 after the end of last season at Portimao", confirmed the Australian. "It was nice to shake off a bit of rust and with Mugello being such a physical circuit it was a good workout!
“The last time I rode a GP machine was at Valencia, which was the 990cc, but the 800cc isn't exactly lacking power and I just spent today getting a feel for it. I can't wait to get back out there tomorrow and on Thursday and hopefully by the end of the session I'll be able to give some useful feedback to Filippo [Preziosi].”
No lap times were released by Ducati.
Bayliss will continue to test the carbon-fibre GP9 on Wednesday and Thursday.
