The Yamaha YZ 125 Cast Piston by Athena, with a 57.94mm bore, is designed for the `97-`21 models and offers top-notch performance for your off-road motorcycle. Known for their high-quality motorcycle parts, Athena's pistons are crafted to deliver excellent reliability and enhanced durability, promising a significant upgrade from standard components.

Engineered with advanced CNC machining tools, the Yamaha YZ 125 Cast Piston ensures dimensional tolerances of less than 0.01 mm, which is crucial for consistent engine performance. Constructed from special high-performance materials like nickel, silica, and aluminum alloys, Athena pistons match the reliability of original equipment pistons, while offering improved resistance and exceptional performance. The smooth profile of the piston aids in maintaining a regular flow and allows for perfect flame propagation, optimizing overall engine efficiency. Additionally, some pistons have skirts treated with a molybdenum disulfide coating applied by screen printing. This coating is specifically designed to reduce friction, further enhancing the piston’s performance and extending its lifespan.
