Top End Gasket Kit - 77 mm - Gas Gas/Yamaha

The Cometic C7905-EST Top End Gasket Kit is designed for high-performance 4-stroke engines, including Gas Gas and Yamaha models with a 77mm bore. This kit includes a base gasket, head gasket, and cylinder O-rings, along with other essential seals for top end repairs. The MLS (multi-layer steel) head gaskets feature embossed outer layers coated with Viton rubber, promoting even torque load distribution across the sealing surface. This design minimizes bore distortion and enhances piston ring sealing, resulting in increased power output. Ideal for naturally aspirated and boosted engines, these gaskets are engineered to withstand high-cylinder pressures and high horsepower demands, making them suitable for aggressive riding and racing conditions. The EST (Extreme Sealing Technology) gasket kit incorporates embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material that effectively dissipates heat away from the combustion ring, preventing hot spots and gasket failure. Made in the USA, this gasket kit ensures durability, reliable sealing, and optimized performance for your high-performance motorcycle engine. Compatible with Gas Gas and Yamaha models with a 77mm bore, this kit is a crucial upgrade for enthusiasts seeking enhanced engine sealing and longevity.
