It has just been reported that factory Yamaha 450-class racer Josh Hill will not be racing the Washougal AMA Motocross this weekend as he is still battling an injured back. Hill will be replaced by rookie pro Scott Champion, from Menifee, California. Champion has been riding the 250 class, but for this coming weekend he’ll ride Hill’s YZ450F in the premier class, and be pitted under the factory rig.
