Cometic's .018" Multi-Layer Steel head gasket for the Yamaha YZF-R1 (2004–2006), 79mm bore, provides a robust replacement head seal. The MLS construction conforms load distribution across the sealing area and is engineered to require less clamp load, reducing bore distortion. Cometic specifies no sealants or re-torque in typical use, offering a straightforward sealing solution matched to the R1’s factory-style requirements.
