When the going gets tough, nothing helps you go the distance like the 2022 Honda CRF450RX. Packed with a lot of the same innovations as our 450R motocrosser, the CRF450RX is fine-tuned for enduro racing mastery. The compact Unicam® engine offers responsive power over everything. Innovations like Honda Selectable Torque Control let you maximize traction for different conditions. A lightweight chassis, 18-inch rear wheel, hydraulic clutch and special suspension settings help you take on varied terrain. And Honda’s famous reliability means this bike can take a beating and keep on competing. It makes cutting through the competition feel more like cutting fresh tracks.
