In this marvellous video you can see a Yamaha R1 2008 Replica Valentino Rossi, prepared by the Brasilians from Motostore.
With this kind of a bike, maybe Rossi could run shoulders with the likes of Noriyuki Haga in the Superbike world.
On Motors CO you can find all the details and costs of this tune-up, around 25,000 dollars.
