I've just signed up to play Fantasy Road Race 2009:
There's a top prize of a Yamaha R6!
Similar to other Fantasy Leagues, you select a motorcycle team consisting of six riders - two from each classification of MotoGP, World Superbikes and British Superbikes - all from your budget of £10 million.
If you join the "Your Bike Life Racers!", you could win *$100*, among other prizes, if you win the league!
You can get more details from this link:
It sounds like it could be a lot of fun!
