Product description
The Cometic Top End Gasket Kit For Gas Gas MC250 2024-2025 is part of the latest collection from Cometic.
Features:
- Top end gasket kit includes correct base, head gasket and cylinder O-rings as well as other top end specific O-rings or seals needed for R&R of top end
- MLS head gaskets promote an even torque load across the gasket sealing surface, providing less bore distortion and better piston ring seal for more power
- 4-stroke head gaskets are made to perform on todayâ€s highest-output 4-stroke naturally aspirated and boosted machines, utilizing a multi-layered steel design with the outer layers being embossed and coated with a Viton rubber coating; these head gaskets are designed to meet the demands of today's high-horsepower, high-cylinder-pressure engines
- EST (Extreme Sealing Technology) gasket kit includes embossed stainless steel head, base and rocker gaskets covered with a proprietary rubber material
- Head gasket material allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface to eliminate hot spots and gasket failure
- Made in the USA
