■ High seal to prevent combustion power, low friction for smooth up/down movement, high heat efficiency to release piston heat. These elements are embodied in a different approach to creating a highly durable piston with low power loss.
■ The top land has 5 grooves cut and is a forged piston for high rotations and high output with improved seal by the labyrinth effect.
(Recommended piston clearance: 0.05 mm)
