This Top End Piston Kit includes a forged 4-stroke piston and a top end gasket kit. Athena pistons are made of special high-performance aluminum alloy with a high silicon content, ensuring reliability, greater resistance, and excellent performance. The smooth profile ensures regular flow and perfect flame propagation. Some piston skirts are treated with a molybdenum disulfide coating to reduce friction, enhancing performance and durability. Piston rings, made in Japan, have wear-resistant coatings (PVD or chromium nitride) for increased retention and durability. Athena gasket kits are developed with over 40 years of experience, using advanced technology and strict manufacturing parameters for optimal sealing.
