Athena 02-25 Yamaha YZ 85 52.96mm Replacement 2T Forged Piston (For Athena Big Bore Kit)

This Athena 52.96mm 2-stroke forged piston is specifically made for the Yamaha YZ 85 model years 2002-2025, and it's intended for use with Athena Big Bore Kits. When you're looking to get more out of your engine, a well-built forged piston like this one can make a notable difference in performance and durability compared to cast pistons.

Forged pistons are constructed from a solid block of aluminum that's heated and then hammered into shape under immense pressure. This process creates a denser, stronger grain structure than you get with cast pistons, making them more resistant to the high pressures and temperatures found in a performance engine. This particular piston is designed to be a direct replacement part within an Athena Big Bore Kit, ensuring it works seamlessly with other components in the kit for optimal function.

Because this piston is part of a Big Bore Kit, it's important to ensure you have the correct kit installed on your Yamaha YZ 85. This piston is not CARB approved and cannot be shipped to California.
