About this product
Ensure peak performance and reliability for your high-output motorcycle engine with the Cometic Hi-Performance MLS Top End Gasket Kit. Engineered with advanced multi-layer steel (MLS) technology and Extreme Sealing Technology (EST), this kit provides superior sealing for demanding 4-stroke applications.
Description
The Cometic Hi-Performance MLS Top End Gasket Kit is meticulously designed to meet the rigorous demands of today's most powerful 4-stroke naturally aspirated and boosted engines. Utilizing a robust multi-layered steel (MLS) construction, these gaskets 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. Each 4-stroke head gasket is crafted with outer layers embossed and coated with a durable Viton rubber, ensuring exceptional sealing integrity under high temperatures and pressures.
This comprehensive kit includes all essential components for a top-end overhaul, such as the correct base, head gasket, and cylinder O-rings, along with other specific O-rings and seals required for removal and reinstallation. Cometic's proprietary Extreme Sealing Technology (EST) further enhances durability, featuring embossed stainless steel head, base, and rocker gaskets covered with a specialized rubber material. This advanced gasket material is engineered to efficiently draw heat away from the combustion ring, dissipating it evenly across the gasket surface. This crucial feature eliminates dangerous hot spots and prevents premature gasket failure, ensuring long-lasting performance for your engine with a 105.50 mm (4.154") bore and a precise 0.69 mm (0.027") thickness.
