FULL DESCRIPTION
Athena Forged Piston Kit 53mm for Big Bore Cylinder
This Athena Piston Kit is engineered for performance and reliability, featuring a forged piston crafted from a special high-performance aluminum alloy with a high silicon content. Manufactured using advanced CNC machining for precise tolerances, this piston ensures superior resistance and excellent performance, comparable to or exceeding Original Equipment (OE) standards.
Key Features:
- Forged Piston: Constructed from a high-performance aluminum alloy with high silicon content for enhanced durability and performance.
- Precision Machining: Utilizes cutting-edge CNC machining tools to achieve dimensional tolerances of less than 0.01 mm.
- Optimized Profile: Features a smooth piston profile for regular flow and perfect flame propagation.
- Reduced Friction: Some piston skirts are treated with a molybdenum disulfide coating applied by screen printing to further reduce friction, enhancing performance and durability.
- High-Quality Rings: Includes piston rings produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased retention and durability, designed to adapt perfectly to the cylinder liner even at low tangential load.
- Complete Kit: This kit contains the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable.
