There’s an interesting article on Crash.net, which takes a look at the number of times Valentino Rossi has won races when he’s ridden a bike with a special one-off livery, versus the number of times he’s won aboard a bike with his usual, ‘normal’ colours.
Between 2001 to 2008, Rossi rode with special liveries in a total of eight races, taking two wins and six podium finishes. This means a special livery win rate of 25% and podium rate of 75%. Now, leaving out the races where Rossi did ride with a special livery, his win rate in the premier class has been no less than 48%, while his podium rate has been 76%.
So, according to these numbers, Rossi should avoid using a special livery in any of the remaining races in this season if he doesn’t want to take any chances with winning the 2009 MotoGP world championship!
