Description

When you're pushing your YZ250F to its limits, stock pistons become your weak point—compromising power delivery and ring seal integrity under sustained high RPM. The ATHENA Piston Kit delivers the durability and precision of OE engineering with measurably superior resistance to heat and wear, giving you reliable performance lap after lap. Engineered with high-silicon aluminum alloy and PVD-coated compression rings, this kit reduces friction losses while maintaining critical cylinder tolerances that keep combustion consistent.

  • Material: High-silicon aluminum alloy
  • Manufacturing: CNC reverse extrusion
  • Ring coating: PVD chromium nitride
  • Friction: Reduced vs. OE
  • Flame propagation: Optimized profile
  • Ring wear: Significantly increased
  • Origin: Made in Japan
  • Fitment: YZ250F specific
  • Installation: Bolt-on replacement
  • Included: Gasket set
