Product Details
If you're rebuilding the top end of your 2002-2018 Yamaha YZ 85, a new piston is a key part of the job. This cast piston from Athena is made with special nickel, silica, and aluminum alloys, giving you the same reliability as the original equipment piston but with added resistance and performance.
Athena uses advanced CNC machining tools to ensure the piston's dimensions are held to very tight tolerances, less than 0.01 mm. This precision helps ensure a smooth profile for regular flow and proper flame propagation inside the cylinder. Some pistons also feature a molybdenum disulfide coating on the skirt, applied by screen printing, which further reduces friction for improved performance and durability.
