About this part

Product Details

This is an Athena 4-stroke forged piston designed for the 2018 through 2024 Honda CRF 250 R. It features an 84.95mm bore and is constructed from special high-performance alloys, including nickel, silica, and aluminum. This construction aims to match the reliability of the original equipment piston while offering increased resistance and better performance.

Athena uses advanced CNC machining tools to ensure very tight dimensional tolerances, less than 0.01 mm, for a precise fit. The piston's smooth profile is intended to promote regular airflow and efficient flame propagation within the combustion chamber. These pistons are made using a reverse extrusion process, a method that contributes to their overall strength and consistency.
