About this product
Ensure peak engine performance and reliability with the Cometic Hi-Performance Top End Gasket Kit, specifically engineered for demanding 4-stroke motorcycle engines. This comprehensive kit provides all the essential components for a complete top end rebuild, delivering unmatched sealing integrity and durability.
Description
Designed for today's highest-output 4-stroke naturally aspirated and boosted machines, the Cometic Top End Gasket Kit utilizes advanced Multi-Layer Steel (MLS) head gaskets. This innovative design promotes an even torque load across the gasket sealing surface, significantly reducing bore distortion and enhancing piston ring seal for increased power output. Each MLS head gasket features outer layers that are embossed and coated with a high-grade Viton rubber, ensuring exceptional resilience against extreme temperatures and pressures. The Extreme Sealing Technology (EST) gasket kit further incorporates embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized head gasket material efficiently draws heat away from the combustion ring, dissipating it evenly across the gasket surface to eliminate hot spots and prevent premature gasket failure. Made in the USA, this kit is built to meet the rigorous demands of high-horsepower, high-cylinder-pressure engines, providing a reliable seal for your 95.00 mm (3.750") bore and a precise 1.02 mm (0.040") thickness.
