Valentino Rossi has shared images of him undergoing a seat fit with Mercedes as excitement builds for his highly anticipated ride swap with Lewis Hamilton.
Rossi is set to get his hands on one of the Silver Arrows' title-winning cars, while Hamilton will get to sample MotoGP machinery for the first time.
The seven-time premier class world champion on two wheels, Rossi has previously driven Formula 1 cars with Ferrari, while Hamilton tested World Superbikes motorcycles a year ago.
And the 40-year-old offered a peek behind the curtain as preparations for the swap continue.
