Cometic Hi-Performance 4-Stroke Top End Gasket Kit

Ensure a flawless engine rebuild and maximum performance for your 4-stroke motorcycle with the premium Cometic 4-Stroke Top End Gasket Kit. This comprehensive kit provides all necessary components for the removal and replacement (R&R) of your top end, including precision-engineered head and base gaskets, along with crucial cylinder O-rings and other top-end specific seals.

Description

Designed for today’s highest-output 4-stroke naturally aspirated and boosted machines, this Cometic Hi-Performance Top End Gasket Kit is engineered to deliver superior sealing and durability. At its core are advanced MLS (Multi-Layer Steel) head gaskets, meticulously crafted to 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 and efficiency from your engine. The MLS head gaskets feature a multi-layered steel construction, with outer layers embossed and coated with a high-performance Viton rubber. This robust combination is built to withstand the extreme demands of high-horsepower, high-cylinder-pressure engines.

The kit also incorporates Cometic's renowned EST (Extreme Sealing Technology), featuring embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized head gasket material plays a critical role in drawing heat away from the combustion ring, ensuring it dissipates evenly across the gasket surface. This active heat management eliminates hot spots, drastically reducing the risk of gasket failure and prolonging engine life. With a precise bore size of 101.00 mm (3.976") and a thickness of 0.69 mm (0.027"), this kit provides the exact fitment and sealing integrity required for a professional-grade engine rebuild. Proudly made in the USA, this high-performance gasket set is the ideal choice for motorcycle enthusiasts and technicians seeking uncompromising quality and reliability.
