Cometic Top End Gasket Kit for Honda XR650, 101 mm (C7681)

The Cometic C7681 Top End Gasket Kit is designed for Honda XR650 engines requiring reliable sealing during top-end service. This comprehensive kit includes the correct base gasket, head gasket, cylinder O-rings, and additional top-end-specific O-rings or seals needed for removal and replacement of the top-end components. The kit helps simplify installation by providing the essential sealing components in one application-focused package.
Cometic uses a multi-layer steel (MLS) head gasket design to promote even torque distribution across the sealing surface. This helps reduce bore distortion and support improved piston ring sealing for dependable engine performance. Built for today’s high-output four-stroke engines, the gasket construction is suited to naturally aspirated and boosted applications where elevated cylinder pressures demand consistent sealing performance.
The Cometic C7681 also incorporates Extreme Sealing Technology (EST), featuring embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber coating. The head gasket material helps draw heat away from the combustion ring and distribute it evenly across the gasket surface, helping reduce hot spots and the risk of gasket failure. Manufactured in the USA, this Cometic gasket kit is a practical choice for Honda XR650 rebuilds, top-end maintenance, and performance-focused engine service.
