Description
The Cometic Yamaha YFZ450 Top End Gasket Kit is a high-performance gasket solution designed for complete top-end rebuilds. It includes all necessary components such as head gaskets, base gaskets, cylinder O-rings, and other specific O-rings or seals required for top-end maintenance. Utilizing advanced materials and engineering, these gaskets deliver exceptional sealing performance, even under the extreme conditions of modern high-output engines. The kit features Multi-Layered Steel (MLS) head gaskets with embossed outer layers coated in Viton rubber for superior sealing. This design promotes even torque distribution, minimizes bore distortion, improves piston ring sealing, and enhances overall power output. The head gasket material efficiently dissipates heat across its surface to prevent hot spots and reduce the risk of gasket failure. Additionally, the kit incorporates Extreme Sealing Technology (EST), which uses stainless steel gaskets coated with a proprietary rubber material to ensure critical sealing and superior durability. Designed to meet and exceed OEM specifications, this kit is engineered to handle the demands of high-horsepower, high-cylinder-pressure engines. It also includes valve stem seals and exhaust gaskets for a comprehensive rebuild. This gasket kit is ideal for Yamaha YFZ450 models and is built to withstand modern engine performance challenges, such as higher cylinder pressures, extreme temperatures, and increased horsepower. Constructed from premium materials like spring steel or graphite, these gaskets are resistant to fuels, coolants, and oils, ensuring reliability and longevity for your engine.
