The AMA Pro Road Racing series makes its third annual stop in Utah this weekend at Miller Motorsports Park in Tooele.
All four classes of motorcycles will race, including the top National Guard SuperBike series on both Saturday and Sunday.
Three-time defending National Guard SuperBike champion Josh Hayes, atop the standings with 223 points after winning six of the last seven events, will look to extend his lead over Josh Herrin, last season's rookie of the year who sits just 11 points back. Both riders race for the Monster Energy Graves Yamaha team. Colombian Martin Cardenas, in third place with 207 points, is the only other racer who poses a threat to Hayes' bid for a fourth straight championship.
