About This Product
These Cometic cylinder base gaskets suit both front and rear cylinders on 1957–1971 XL900 Sportster models. At .012" thick, this precision die-cut fiber gasket features a robust black composite construction with four corner bolt holes and the distinctive Cometic branding visible across the surface. Manufactured from a premium high-temperature, high-density material that resists creep and fuel degradation, it requires no re-torquing after installation and needs no additional sealants. Asbestos-free and dimensionally stable, this gasket replaces OEM reference 16774-57, providing reliable sealing for your Ironhead top-end rebuild.
Manufacturer part number: C9699.
