FULL DESCRIPTION
Athena Forged Piston Kit B 77mm for Kawasaki KX 250
Upgrade your motorcycle's performance and reliability with this high-quality Athena forged piston kit. Designed and engineered in Italy, this piston kit utilizes advanced manufacturing techniques to deliver exceptional durability and power.
Athena pistons are crafted from a special high-performance aluminum alloy with a high silicon content, ensuring they meet or exceed Original Equipment (OE) standards. Manufactured using cutting-edge CNC machining, these pistons boast dimensional tolerances of less than 0.01 mm for a precise fit and optimal operation.
Key Features:
- Forged Piston: Constructed from a high-performance aluminum alloy for superior strength and resistance.
- Precision Machining: CNC machined to exacting standards for perfect fitment and performance.
- Reduced Friction: Some piston skirts feature a molybdenum disulfide coating, applied by screen printing, to further reduce friction, enhance performance, and improve durability.
- Advanced Ring Technology: Piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased lifespan and durability. They ensure less friction with the cylinder, leading to higher performance.
- Complete Kit: Includes the piston, pin, circlips, and piston rings, with all components being replaceable and interchangeable.
- Engine Dynamometer Tested: Each piston undergoes rigorous testing on engine dynamometer benches and on track to validate performance in extreme conditions.
