About this part

Product Details

This is an Athena forged piston, measuring 80.43mm, designed for specific Polaris TRAIL 350 BOSS L 2X4 models. Athena has been making motorcycle spare parts for over 40 years, and this piston is built using a reverse extrusion process with advanced CNC machining to ensure precise dimensions, holding tolerances to less than 0.01 mm.

The piston is made from a special alloy of nickel, silica, and aluminum. This material choice aims to match the reliability of original equipment pistons while offering increased resistance and better performance. The smooth surface profile helps with regular airflow and proper flame propagation within the cylinder, contributing to a more efficient burn.
