Cometic Hi-Performance Top End Gasket Kit for 4-Stroke

The Cometic Hi-Performance Top End Gasket Kit is engineered to provide superior sealing and reliability for your 4-stroke motorcycle engine. This comprehensive kit includes all essential gaskets and O-rings for a complete top-end rebuild or refresh, ensuring optimal engine performance and longevity.

Description

Designed for today's most demanding engines, the Cometic Hi-Performance Top End Gasket Kit offers unparalleled sealing integrity. This kit is specifically tailored for 4-stroke engines, featuring advanced Multi-Layer Steel (MLS) head gaskets that promote an even torque load across the sealing surface. This innovative design significantly reduces bore distortion, leading to a better piston ring seal and ultimately, more power for your machine. Cometic's MLS head gaskets are built to perform on high-output, naturally aspirated, and boosted engines, utilizing an embossed multi-layered steel design with outer layers coated in Viton rubber for extreme durability.

The kit incorporates Cometic's proprietary Extreme Sealing Technology (EST), which includes embossed stainless steel head, base, and rocker gaskets covered with a specialized rubber material. This advanced material composition allows heat to be efficiently drawn away from the combustion ring and dissipated evenly across the gasket surface, effectively eliminating hot spots and preventing premature gasket failure. With a precise bore size of 82.00 mm (3.228") and a gasket thickness of 0.69 mm (0.027"), this Cometic gasket kit provides the exact fit and sealing performance required for high-horsepower, high-cylinder-pressure applications. Proudly made in the USA, this kit ensures premium quality and reliable performance for your motorcycle.
