Upgrade your 2-stroke off-road engine with the ATHENA P4C0664045001A Piston Kit with Gaskets. Designed for select Husqvarna and KTM applications, this kit combines a high-performance piston, piston rings, and a precision gasket set to support dependable engine operation, effective sealing, and consistent performance. The piston is manufactured from a special aluminum alloy with high silicon content, delivering OE-level reliability while improving resistance to operating stresses and wear.
The piston’s smooth profile promotes regular airflow and efficient flame propagation throughout the combustion chamber. ATHENA produces its 2-stroke off-road pistons using computer numerical control (CNC) machinery, helping maintain precise manufacturing tolerances and consistent component quality. The included piston rings are engineered to provide a strong seal against the cylinder walls while reducing friction, supporting responsive performance and efficient power transfer.
The accompanying gasket kit is produced according to strict manufacturer specifications. Gaskets are manufactured from carefully selected raw materials and receive surface treatments designed to compensate for surface irregularities. A material stress-relieving process further supports reliable sealing in critical areas, helping protect against leaks and promoting long-term engine durability. This ATHENA kit is a practical choice for engine rebuilding, maintenance, or performance-focused replacement on compatible Husqvarna and KTM 2-stroke off-road motorcycles.
Please verify application compatibility and piston specifications before installation. Professional installation is recommended to ensure correct fitment, ring placement, gasket positioning, and engine assembly procedures.
