Description
The Cometic EST (Extreme Sealing Technology) Top End Gasket Kit is engineered for high performance and reliability. Designed for the Suzuki RM-Z250 with an 82mm bore, this kit includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. The head gasket material efficiently draws heat away from the combustion ring, dissipating it evenly across the gasket surface to help prevent hot spots and gasket failure. The kit contains all necessary gaskets, seals, and O-rings required to rebuild the top end from the cylinder base upward. Suitable for today’s high-output, high-cylinder-pressure 4-stroke engines. Made in the USA.
- Includes correct base, head gasket, cylinder O-rings, and other top end specific O-rings/seals
- Multi-layer steel (MLS) design for even torque load, less bore distortion, and better piston ring seal
- Embossed and coated with Viton rubber for superior sealing
- For Suzuki RM-Z250 (2010-2023) with 82mm bore
