PISTON KIT B 82MM KTM/HUSKY 250 13-22, ATHENA S4F08200005B 276CC BIG BORE, KIT B

Athena Forged Piston Kit B - 82mm

Upgrade your motorcycle's performance with the Athena Forged Piston Kit B. Engineered by Athena, a leader in motorcycle spare parts for over 40 years, this piston kit is designed for high-performance applications. Each piston is forged using a special high-performance aluminum alloy with a high silicon content, ensuring both reliability and enhanced durability.

Utilizing cutting-edge CNC machining tools, Athena guarantees dimensional tolerances of less than 0.01 mm for precise fitment. This piston features a perfectly smooth profile for optimal air flow and flame propagation. Some pistons include a molybdenum disulfide coating on the skirts, applied via screen printing, to further reduce friction and boost performance and longevity.

The piston rings in this kit are produced in Japan and feature wear-resistant coatings (PVD or chromium nitride) to increase durability and lifespan. These rings are designed to perfectly adapt to the cylinder liner even under low tangential load, minimizing friction and maximizing performance.

This comprehensive kit includes the piston, piston pin, circlips, and piston rings. All components are replaceable and interchangeable, providing flexibility for maintenance.
