Athena 15-18 Yamaha WR 250 F 80.96mm 4T Forged Racing Piston

Forged from a special aluminum alloy containing nickel and silica, this Athena piston is built for high-performance 4-stroke applications. The reverse extrusion process and CNC machining to tolerances of less than 0.01 mm ensure a precise fit and consistent operation within your 2015-2018 Yamaha WR 250 F's engine. This piston is designed to offer the same reliability as an original equipment piston but with improved resistance and performance for demanding use.

The smooth profile of this piston helps promote regular airflow and efficient flame propagation, contributing to better overall engine performance. Athena has been making motorcycle spare parts for over 40 years, and this piston reflects their experience in creating durable and high-performing engine components. While it matches OE reliability, it's constructed with advanced materials to handle more stress and deliver enhanced output.
