Athena 77.97 mm Piston Kit with Gaskets for Kawasaki Off-Road Motorcycles (P5F0780071004B)

The ATHENA P5F0780071004B Piston Kit with Gaskets is engineered for Kawasaki 4-stroke off-road motorcycles requiring dependable performance and OE-level reliability. Constructed from high-performance aluminum alloy with a high silicon content, the piston offers excellent strength, heat resistance, and durability under demanding riding conditions. Its 77.97 mm piston size supports precise fitment when matched to the appropriate engine application and service specifications.
The piston’s smooth profile promotes consistent gas flow and efficient flame propagation, helping support responsive engine performance. ATHENA manufactures its 4-stroke off-road pistons using reverse extrusion and CNC machining processes for accurate production and dependable quality. The included piston rings are designed to reduce friction between the rings and cylinder, helping improve efficiency and performance while supporting reliable sealing.
This kit includes wear-resistant piston rings manufactured in Japan with PVD or chromium nitride coatings. These coatings help improve ring retention and extend service life, making the assembly suitable for riders, technicians, and performance-focused rebuilds. Gaskets are included for a more convenient installation, but all components should be verified against the motorcycle’s year, model, engine specifications, and manufacturer service requirements before installation.
