Yamaha MY24 YZ85 Large Wheel

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.
