Product Details

This Cometic head gasket is built with a .018 inch thickness and a 78mm bore, specifically made for the 2004-2006 Yamaha YZF-R1. When you're rebuilding the top end of your motorcycle's engine, a reliable head gasket is crucial for sealing the combustion chamber and coolant passages. This part ensures proper compression and prevents leaks between the cylinder head and the engine block.

Cometic uses multi-layer steel (MLS) construction for these gaskets, which offers good sealing performance and durability. The layers are embossed and coated with a high-temperature sealant that helps it conform to the mating surfaces, even with minor imperfections. This design helps maintain consistent clamping force across the entire sealing surface, which is important for preventing blow-offs under high combustion pressures.

If you're in the process of a top-end rebuild or repair on your YZF-R1, this gasket is designed to fit right and perform reliably. Always refer to your service manual for specific installation procedures and torque specifications to ensure a proper seal.
