This piston is suitable for motocross setups and fits, among others, the YAMAHA YZ 80 (models 2000-2001) indicated in the compatibility. Before installation, check the cylinder bore and the oversize correspondence to ensure proper piston/cylinder clearance. For installation, follow the manufacturer's recommendations (tolerances, installation direction, and torque) and check the condition of the cylinder and rings.
