Athena 21-23 Yamaha WR 450 F 96.96mm 4T Forged Piston

This Athena forged piston is made from a special aluminum alloy incorporating nickel and silica. This combination of materials is chosen to give you the same reliability you'd expect from an original equipment piston, but with added resistance and better performance for your 2021-2023 Yamaha WR 450 F. The piston is manufactured using advanced CNC machining tools, which hold tolerances to less than 0.01 mm, ensuring a precise fit inside the cylinder.

The forging process itself, using reverse extrusion, along with the perfectly smooth profile, helps ensure regular fuel flow and proper flame propagation. This means you get a well-built piston that works efficiently with your engine's combustion cycle. Athena has been making motorcycle spare parts for over 40 years, so they know how to build components that hold up.
