Cometic C8727 MLS Head Gasket Bore Thickness - 77mm 027

The Cometic C8727 is a Multi-Layer Stainless Steel (MLS) head gasket featuring a 77mm bore and 0.027 inch compressed thickness, designed for 2004-2007 Honda CBR1000RR motorcycles. This high-performance gasket is constructed from multiple layers of stainless steel for additional strength over traditional gaskets, making it ideal for both stock and high-performance applications.

Key Features:

• Multi-layer steel construction with embossed Viton-coated stainless steel outer layers providing superior seal and excellent rebound characteristics
• Load-controlled embossments help conform load distribution across the sealing area, creating an exceptional seal by requiring less clamp load and resulting in less bore distortion
• Stainless-steel outer layers utilize a rubber-binder coating that features high-temperature and chemical-resistant polymers
• Proprietary high temperature coatings along with embossments provide a micro seal for fluids against the head and block surface
• No sealants or re-torque required when properly installed on prepared surfaces
• Requires smooth, flat head and deck surfaces with a surface finish of 50 RA (roughness average) or finer for proper sealing

MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures, making this gasket suitable for demanding racing and performance applications. Made in the USA, Cometic gaskets are trusted by professional racers and performance enthusiasts worldwide for their proven reliability under extreme conditions.
