The Athena P5F0780074001B piston kit is engineered for four-stroke Husqvarna and KTM off-road motorcycles, providing dependable performance and durability for demanding riding conditions. Constructed from a high-performance aluminum alloy with a high silicon content, this piston is designed to deliver OE-level reliability while offering improved resistance to heat, wear, and operating stress. The kit includes the piston, piston rings, and gaskets for a complete replacement solution.
The piston’s smooth profile promotes consistent airflow and efficient flame propagation, supporting reliable combustion and responsive engine performance. Manufactured using reverse extrusion and precision CNC machining, the Athena piston is produced to maintain accurate fitment and consistent dimensional quality. Its design is intended to support the performance characteristics required by modern four-stroke off-road engines.
The included piston rings are manufactured in Japan and feature wear-resistant PVD or chromium nitride coatings. These coatings help reduce friction between the rings and cylinder, which can contribute to improved engine efficiency and performance while extending ring service life. The reduced-friction design also supports effective sealing and reliable oil control throughout the engine’s operating range.
Designed as a direct replacement component, the Athena P5F0780074001B piston kit combines durable materials, precision manufacturing, and coated piston rings for dependable engine rebuilding or maintenance. Verify motorcycle year, model, and engine specifications before installation to confirm proper application.
