The COMETIC C7855 Top End Gasket Kit is designed for Yamaha motorcycles and provides a comprehensive solution for top end rebuilds. This kit includes a high-quality MLS head gasket, base gasket, and cylinder O-rings, along with other essential seals and O-rings needed for a precise and reliable top end assembly. Crafted to meet the demands of high-performance engines, the MLS head gasket features a multi-layered steel construction with embossed outer layers coated with Viton rubber, ensuring even torque distribution and superior sealing performance. This design helps prevent bore distortion and enhances piston ring sealing, resulting in increased power output and engine efficiency. Suitable for Yamaha models with 4-stroke engines, both naturally aspirated and boosted, this gasket kit is engineered to handle high-cylinder pressure and extreme operating conditions, making it an ideal choice for performance enthusiasts and professional rebuilds. The EST (Extreme Sealing Technology) head gasket utilizes embossed stainless steel covered with a proprietary rubber material that effectively manages heat dissipation, reducing hot spots that can lead to gasket failure. Whether you're restoring a vintage Yamaha or upgrading a high-performance build, this kit provides durable, reliable sealing components to ensure optimal engine performance. Made in the USA, the COMETIC C7855 gasket kit is compatible with Yamaha models including, but not limited to, YZF, FZ, and WR series with 4-stroke engines, and is designed to meet the rigorous demands of today's high-horsepower, high-compression engines.
