Cometic 4-Stroke Top End Gasket Kit

Ensure peak engine performance and reliability for your 4-stroke motorcycle with the premium Cometic 4-Stroke Top End Gasket Kit. Engineered for demanding conditions, this high-performance gasket kit provides a complete solution for your top-end rebuild or maintenance.

Description

The Cometic Top End Gasket Kit is meticulously designed to meet the rigorous demands of today's highest-output 4-stroke naturally aspirated and boosted engines. At its core are the advanced MLS (Multi-layer Steel) head gaskets, which are crucial for promoting 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. With a precise bore size of 106.00 mm and a thickness of 0.69 mm (0.027"), these gaskets are built for exact fitment and optimal compression.

Further enhancing its durability and sealing capability, this high-performance gasket kit features Cometic's proprietary EST (Extreme Sealing Technology). This includes embossed stainless steel head, base, and rocker gaskets, all covered with a specialized rubber material. The outer layers of the MLS head gaskets are embossed and coated with a Viton rubber coating, ensuring exceptional resistance to heat and chemicals. This superior gasket material effectively draws heat away from the combustion ring, dissipating it evenly across the gasket surface to eliminate damaging hot spots and prevent premature gasket failure. Made in the USA, this kit delivers the quality and reliability discerning riders and mechanics expect for their motorcycle engine rebuilds.
