Timeless, classic styling in a high-quality custom master cylinder. For use with an M10 x P1.25 banjo bolt, which is the same size used on the OEM master cylinders on most Honda, Yamaha, Kawasaki and Suzuki models 02 and newer (many Ducati and older Suzuki applications are M10 x P1.0 and will require a new banjo bolt). Not compatible with DOT 5 silicone brake fluid. Designed to be used on 7/8″ handlebars and clip-ons with a 15 downward angle.
