PISTON KIT B 88mm KTM 350 11-22, Comp. 13.5:1, ATHENA S4F08800004B HUSQVARNA

Athena Forged Piston Kit B - 88mm Bore, 13.5:1 Compression

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 is designed for exceptional reliability and enhanced performance. Crafted using cutting-edge CNC machining tools, it ensures dimensional tolerances of less than 0.01 mm, guaranteeing a perfect fit and optimal function.

This piston is constructed from a special high-performance aluminum alloy with a high silicon content. This advanced material offers superior resistance and excellent performance compared to OE pistons, while maintaining the same level of reliability. The perfectly smooth profile promotes regular airflow and ideal flame propagation, contributing to a more efficient combustion process.

For even greater performance and durability, some Athena pistons feature a molybdenum disulfide coating applied by screen printing to the piston skirts. This treatment significantly reduces friction, further enhancing both performance and lifespan.

Athena's commitment to quality is evident in their rigorous testing procedures. Each piston is engineered in Italy and subjected to extensive testing on engine dynamometer benches under progressive stress loads, and then validated on track in the most extreme conditions. This ensures that every piston meets the highest quality standards, delivering both performance and reliability.

This comprehensive kit includes the piston, piston pin, circlips, and piston rings. The piston rings, produced in Japan with wear-resistant coatings (PVD or chromium nitride), are designed to reduce friction with the cylinder, leading to higher performance and increased durability. They are engineered to adapt perfectly to the cylinder liner, even under low tangential load.
