Tuned-Up: Ben Lamay’s Rock River Yamaha YZ450F

Scott Lillis is the man in charge of getting Ben LaMay’s Rock River Yamaha YZ450F race-ready each weekend, and we must say that the tuner is one of the most well-spoken guys in the pit area that we have talked to. He and his rider both know every inch of the machine and consistently place within the top-20 indoors and out. We grabbed Lillis for this week’s installment of Behind Bars, where he went into great detail on what it takes to build a competitive bike.
