FULL DESCRIPTION
Athena Forged Piston Kit - Big Bore Upgrade
Enhance your motorcycle's performance with this high-quality Athena forged piston kit. Designed for use with Athena Big Bore cylinder kits, this piston is engineered for superior power and reliability. Athena is a leading manufacturer of motorcycle spare parts with over 40 years of experience, dedicated to providing cutting-edge components for off-road riders.
This piston is crafted using advanced CNC machining tools to ensure exceptional dimensional accuracy, with tolerances less than 0.01 mm. It's made from a special high-performance aluminum alloy rich in silicon, offering the reliability of original equipment (OE) pistons while providing increased resistance and outstanding performance. The smooth piston profile promotes efficient airflow and optimal flame propagation.
Some piston skirts feature a molybdenum disulfide coating, applied through screen printing, to further reduce friction, boost performance, and extend durability. Athena engineers prioritize advanced technical solutions and the highest quality standards, meeting or exceeding OE production specifications for guaranteed performance and dependability.
Each piston is meticulously developed and tested by Athena's R&D department in Italy, undergoing rigorous dynamometer testing and track validation in extreme conditions. This piston kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable. The included piston rings, manufactured in Japan with wear-resistant coatings (PVD or chromium nitride), minimize friction with the cylinder, leading to higher performance and increased durability. These rings are designed for excellent adaptability to the cylinder liner, even under low tangential load.
Key Features:
- Forged piston construction for superior strength and performance.
- Special high-performance aluminum alloy with high silicon content.
