Cometic C10290 MLS Head Gasket Set for RevTech 125ci V-Twin Engines - .040" Thickness, 4.250" Bore

The Cometic C10290 is a premium Multi-Layer Steel (MLS) head gasket set designed specifically for RevTech 125 cubic inch V-twin engines. This pair of high-performance head gaskets features a 4.250-inch bore diameter and .040-inch compressed thickness, providing an optimal seal for high-displacement custom motorcycle builds.

Advanced MLS Construction:

• Multi-layer stainless steel design with three layers for superior strength and durability
• Viton-coated outer layers bonded with .001-inch thick rubber sealant for exceptional sealing performance
• Load-controlled embossments distribute clamping force evenly across the sealing surface
• Non-intrusive rivets secure layers together without compromising seal integrity
• Withstands extreme shearing forces in high-performance V-twin applications

Installation Benefits:

• No additional sealant required—gaskets install dry thanks to factory Viton coating
• No re-torque needed when properly installed on prepared surfaces
• Requires smooth, flat head and deck surfaces with 50 RA surface finish or finer
• Reduces bore distortion compared to traditional composite gaskets

Sold as a pair for complete engine rebuild. Cometic's MLS gaskets are proven in extreme racing conditions and provide reliable sealing for street and performance applications. Ideal for RevTech 125 cubic inch engines requiring precision head gasket solutions.
