Cometic Top End Gasket Kit for KTM 88 mm 4-Stroke Engines (C3605-EST)

The Cometic C3605-EST Top End Gasket Kit is designed for reliable top-end service on compatible KTM 4-stroke engines. This kit includes the correct base gasket, head gasket, cylinder O-rings, and other top-end-specific O-rings or seals required for a complete removal and installation. Part number C3605-EST helps ensure accurate identification when servicing high-output applications.
Cometic uses Extreme Sealing Technology (EST) to combine embossed stainless steel head, base, and rocker gaskets with a proprietary rubber coating. The multi-layered steel head gasket design promotes an even torque load across the sealing surface, helping reduce cylinder bore distortion and support improved piston ring sealing. This construction is engineered for demanding naturally aspirated and boosted 4-stroke engines operating with elevated cylinder pressures.
The head gasket material helps draw heat away from the combustion ring and distribute it evenly across the gasket surface. This helps minimize hot spots and reduce the risk of gasket failure during demanding operation. The embossed outer layers and Viton rubber coating provide dependable sealing performance while accommodating the requirements of modern high-horsepower engines. The Cometic C3605-EST Top End Gasket Kit is made in the USA and is intended for compatible KTM applications using an 88 mm cylinder.
