FULL DESCRIPTION
Athena Forged Piston Kit 100mm for Big Bore Cylinder
This Athena forged racing piston kit is designed for Big Bore cylinder applications. Manufactured by Athena, a leader in motorcycle spare parts for over 40 years, these pistons are produced using advanced reverse extrusion and cutting-edge CNC machining tools to ensure precise dimensional tolerances.
Key Features:
- High-Performance Alloy: Made from a special high-silicon content aluminum alloy, providing OE-level reliability with enhanced resistance and excellent performance.
- Precision Machining: CNC machined to dimensional tolerances of less than 0.01 mm for optimal fit and function.
- Smooth Profile: Designed for a regular flow and perfect flame propagation.
- Friction Reduction: Some piston skirts feature a molybdenum disulfide coating applied by screen printing to further reduce friction, boosting performance and durability.
- Advanced Engineering: Developed with advanced technical solutions and high-quality standards, equal to or better than OE production.
- Rigorous Testing: Each piston is engineered in Italy and tested on engine dynamometer benches and on track in extreme conditions.
- Included Components: The kit contains the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable.
- Premium Piston Rings: Rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased retention and durability, adapting perfectly to the cylinder liner even at low tangential loads.
