it depends if it is super cross or motocross if it was super cross defiantly McGrath and for motocross it has to be Carmichael. But all together it would be Ricky Carmichael all the way. He'd win 9 times out of 10.
Ricky Carmichael is considered one of the best at what he does, competing in Motocross, and he has not been part of any controversies. This makes him a role model for many, however, he has stated that he does not think of himself as a role model.
