Description
Enhance your KTM, Husqvarna, or GasGas 125cc engine with the Athena high-performance piston kit, designed to deliver improved combustion efficiency, reliability, and thermal stability. Manufactured with high-quality materials and precision engineering, this kit optimizes engine performance by reducing mechanical stress and enhancing overall efficiency.
Piston Features:
✅ Flat-top truncated-cone piston with 12° beveled edge – Optimizes compression ratio and enhances turbulence in the combustion chamber for a more efficient burn.
✅ Oil Dots coated walls – Reduces friction and improves lubrication, ensuring smoother operation and extended durability.
✅ Includes two semi-trapezoidal chrome-plated steel rings – Improves gas sealing and provides superior wear resistance under high temperatures.
Bronze Inner Dome – Superior Thermal and Structural Stability
The bronze inner dome ensures excellent thermal resistance and structural stability, maintaining more consistent temperatures and improving heat dissipation within the combustion chamber. Its optimized design enhances the squish effect, promoting better flame propagation for a more uniform and efficient combustion process.
⚠ Important Notes:
- Designed exclusively for use with the Athena piston included in the kit.
- Not compatible with OEM pistons or aftermarket replacements designed for OEM applications.
