Having two products in one kit that work perfectly together for an excellent result. Athena presents on the market the new Top End Piston Kit which includes a forged 4-stroke piston and the top end gasket kit.

Performance, Durability, Smoothing The pistons for 4-stroke Off-Road motorcycles are made by reverse extrusion and produced with state-of-the-art numerical control (CNC) machines. Athena pistons are made of special high-performance aluminum alloy with high silicon content that guarantee the same reliability of the OE piston, while at the same time providing greater resistance and excellent performance. The perfectly smooth profile ensures a regular flow and the perfect flame propagation. Some pistons’ skirts are moreover treated with a molybdenum disulfide coating applied by screen printing which further reduce friction to enhance performance and durability. Piston rings guarantee less friction with the cylinder and therefore a higher performance. The segments included, Made in Japan, have a wear-resistant coatings (PVD or chromium nitride) to increase the retain and the durability. Seal, Reliability Due to its experience in the sector of over 40 years, Athena also boasts an important reputation for the reliability of its gaskets. The Athena gasket kits are based on solid know-how, constant technological development lead by an internal team of engineers and designers; the production carried out strictly following the strict parameters set by the manufacturers. The use of the latest generation lasers guarantees perfect cutting quality. Furthermore, Athena has a wide availability of raw materials, performs surface treatments to compensate for surface irregularities and follows material stress-relieving processes to improve sealing in the most critical areas.
