The Californian Speedway legend is a four-time World Champion and after an injury-ravaged 2017, he's back for more this year. His 'Grin' nickname suits him perfectly as a smile is never far from his face but when the helmet goes on he's fiercely competitive and has a will to win that is like no other. He has over 200 GP's under his belt and almost 90 final's and he's showing no signs of slowing down.
