Description
The Cometic EST (Extreme Sealing Technology) Top End Gasket Kit for Suzuki RM-Z250 with 84mm bore includes embossed stainless steel head, base, and rocker gaskets coated with a proprietary rubber material. The head gasket design helps draw heat away from the combustion ring, promoting even heat dissipation and reducing hot spots to prevent gasket failure. This kit contains all the necessary gaskets, seals, and O-rings required to rebuild the top end from the cylinder base upward. Multi-layered steel (MLS) head gaskets ensure even torque load for less bore distortion and optimal piston ring seal, delivering more power. Designed to meet the demands of high-output, high-cylinder-pressure 4-stroke engines. Made in the USA. Perfect for off-road and high-performance applications.
