As an important entry into the world of competitive motocross, the YZ85 has long been the mini race bike of choice for future champions. Light, nimble and fun with a top shelf suspension, it serves up big-bike spec in a small bike package.

Along with its proven liquid-cooled YPVS-equipped 85cc powerplant, fully adjustable suspension and large diameter brakes, the YZ85 rider ergonomics include a narrow tank design, flat seat, side covers and slim symmetrical radiator shrouds. This enables greater freedom of movement for smooth shifting of body weight and better machine control.
