Grant has had good results with Yamaha in the past, turning a lot of heads as a rookie when he won the 2009 season opener at Anaheim 1 aboard the JGR Yamaha YZ450F. The Californian brings with him a wealth of experience racing in the 450 Supercross class. After some time off in 2018, Grant feels refreshed and looks to deliver solid results for the Factory Yamaha team.
