About this product
Ensure superior sealing and peak performance for your V-Twin engine with the Cometic V-Twin Top End Gasket Kit. Engineered with Cometic's proprietary Extreme Sealing Technology (EST), this comprehensive gasket set provides everything you need for a reliable top-end rebuild, delivering exceptional durability and heat management for demanding motorcycle applications.
Description
The Cometic V-Twin Top End Gasket Kit is meticulously designed to meet the rigorous demands of high-performance 4-stroke motorcycle engines. Utilizing Cometic's renowned EST (Extreme Sealing Technology), this kit features embossed stainless steel head, base, and rocker gaskets, all expertly coated with a proprietary rubber material. This advanced construction is crucial for drawing heat away from the combustion ring, ensuring it dissipates evenly across the gasket surface. This innovative approach effectively eliminates common hot spots and prevents premature gasket failure, enhancing the longevity and reliability of your engine.
Ideal for V-Twin displacements ranging from 88 cc to 1800 cc, including popular 1450 cc and 1690 cc models, this comprehensive top end rebuild kit offers a perfect fit for a 4.125" bore. Each component is crafted to precise specifications, with head gasket thicknesses available in 0.51 mm (0.020") and 0.76 mm (0.030") to accommodate various engine setups. This complete gasket set contains all the necessary gaskets, seals, and O-rings required to meticulously rebuild your engine's top end, from the cylinder base upwards. Proudly made in the USA, the Cometic V-Twin Top End Gasket Kit stands as a testament to quality and precision engineering, providing peace of mind for every ride.
