Ensure peak engine performance and reliability for your motorcycle with the Cometic Hi-Performance 4-Stroke Top End Gasket Kit. Engineered for today's most demanding naturally aspirated and boosted machines, this comprehensive kit provides everything needed for a complete top-end overhaul, delivering superior sealing and power.
Description
The Cometic Hi-Performance Top End Gasket Kit is meticulously designed to meet the rigorous demands of high-horsepower, high-cylinder-pressure 4-stroke engines. Central to its exceptional performance are the Multi-Layer Steel (MLS) head gaskets, which 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 improved engine longevity. Crafted from durable multi-layered steel, the outer layers are embossed and coated with a resilient Viton rubber, ensuring extreme sealing technology (EST) under the most challenging conditions. The head gasket material is engineered to efficiently draw heat away from the combustion ring, dissipating it evenly to prevent hot spots and premature gasket failure. With a precise bore size of 68.00 mm (2.677") and a thickness of 0.46 mm (0.018"), this kit ensures a perfect fit and optimal compression. Proudly made in the USA, Cometic delivers uncompromising quality and performance for your engine rebuilds.
