Engineered for demanding 4-stroke applications, this comprehensive kit provides everything needed for a complete top end rebuild, ensuring a superior seal and enhanced power output for your Yamaha.

Description

Ensure peak engine performance and sealing integrity with this high-performance Cometic Top End Gasket Kit, specifically designed for 99.00mm bore engines like the Yamaha WR 450 F and YZ 450 F (2006-2015). This kit features advanced Multi-Layer Steel (MLS) head gaskets, crucial for today’s highest-output 4-stroke naturally aspirated and boosted machines. The MLS design promotes an even torque load across the gasket sealing surface, which significantly reduces bore distortion and leads to a better piston ring seal, ultimately generating more power. Each 4-stroke head gasket is constructed with embossed outer layers coated in a durable Viton rubber, designed to withstand the extreme demands of high-horsepower, high-cylinder-pressure environments. Utilizing Cometic's Extreme Sealing Technology (EST), the kit includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. This innovative gasket material effectively draws heat away from the combustion ring, dissipating it evenly across the gasket surface to prevent hot spots and premature gasket failure, ensuring long-lasting reliability. Proudly Made in the USA, this motorcycle top end rebuild kit offers unmatched quality.
