The ultimate holeshot machine.
Open-class motocross might as well be called the unlimited class. There’s no room for anything but the best here, and the best keep getting better and better every year. Well, have no fear, because the 2017 Honda CRF450R is here. Major improvements everywhere, especially to the engine’s increased power and peak torque, help drive you to the front of the pack. And when you’re in the lead in the first turn with an empty track in front of you, it’s a whole new kind of race.
