Athena 19-20 Yamaha WR 450 F 96.95mm 4T Forged Piston

Forged from special high-performance alloys including nickel, silica, and aluminum, this Athena piston is built to match the reliability of your Yamaha WR 450 F's original equipment while offering improved resistance and performance. The 96.95mm bore size is precisely machined using advanced CNC tools, ensuring dimensional tolerances of less than 0.01 mm for a perfect fit and consistent operation.

This piston's design, created through reverse extrusion, results in a perfectly smooth profile. This smooth surface helps promote regular airflow and proper flame propagation within the cylinder, contributing to efficient combustion. Athena has been a leader in motorcycle spare parts for over 40 years, and this piston reflects their commitment to using high-performance materials and precise manufacturing to deliver a well-built component for your off-road machine.
