This is Giovanni Bussei:

He rides this XR1200 on the road and even takes it scrambling in the company of his mates (including Valentino Rossi and Marco Simoncelli). Don't let the beard, woolly sweater and pisspot lid fool you, here's what he does on a work day:

He's one of the few knee-down supermoto riders and is blindingly fast.
Despite his ramshackle off-duty appearance he is related to the Agnelli family, the founders of Fiat, but he is famed for taking cold water showers in the paddock and then sleeping in his car, whereas his less affluent colleagues head for a hotel.
Hurrah for yet another fantastically eccentric Italian bike racer.
