Product Details
This Athena forged racing piston is designed for the Yamaha SR 500 4T, using your original cylinder with a bore of 86.92mm. Athena has been making motorcycle spare parts for over 40 years, and this piston is made using a reverse extrusion process and advanced CNC machining tools. This ensures very tight dimensional tolerances, less than 0.01 mm, for a precise fit.
The piston itself is crafted from special high-performance alloys containing nickel, silica, and aluminum. This material blend aims to match the reliability of the original equipment piston while also providing increased resistance and better performance. The smooth surface profile is intended to help with regular airflow and proper flame propagation within the cylinder.
