About this product
Upgrade your motorcycle's engine with the Cometic 4-Stroke Top End Gasket Kit, engineered for superior sealing and performance. This comprehensive kit provides all necessary gaskets and O-rings for a complete top end rebuild, ensuring optimal engine reliability and power.
Description
The Cometic EST Gasket Kit is specifically designed for high-performance 4-stroke engines, providing unmatched sealing integrity crucial for both naturally aspirated and boosted machines. At its core are the advanced Multi-Layer Steel (MLS) head gaskets, meticulously engineered to distribute torque evenly across the sealing surface. This innovative design significantly reduces bore distortion, leading to a superior piston ring seal that translates directly into more power and enhanced engine efficiency. Each MLS head gasket features outer layers embossed and coated with a durable Viton rubber, making them resilient against the extreme pressures and temperatures of today's highest-output engines. This Extreme Sealing Technology (EST) ensures consistent performance and reliability under the most demanding conditions. The proprietary rubber material covering the embossed stainless steel head, base, and rocker gaskets actively draws heat away from the combustion ring, preventing hot spots and premature gasket failure. With a precise bore size of 97.00 mm (3.818") and a thickness of 0.69 mm (0.027"), this kit provides the exact fitment needed for a flawless top end rebuild. Proudly made in the USA, Cometic delivers a complete solution for maintaining or upgrading your motorcycle's engine with confidence.
