About this part

Product Details

Athena has been making motorcycle spare parts for over 40 years, and they've brought that experience to their new line of 4-stroke off-road forged pistons. This piston, part number S4F08600001A, is made using a reverse extrusion process and then machined with advanced CNC tools to ensure it's within 0.01 mm of its specified dimensions. It's built from a special alloy of nickel, silica, and aluminum, which gives you the same dependability as an original equipment piston but with added strength and better performance.

The smooth surface of this Athena piston helps with consistent airflow and proper flame spread inside the cylinder. This means you get a well-built part that's designed to handle the demands of off-road riding while maintaining reliability.
