Wilwood Right-Hand Long-Lever Handlebar Master with 5/8-inch Bore and Integral Reservoir

The right-hand long-lever assembly places the master cylinder and fluid reservoir together on the handlebar. A three-position hydraulic lock is incorporated in the lever mechanism, while the translucent reservoir permits fluid-level inspection. The manufacturer is Wilwood Engineering of Camarillo, California, established by Bill Wood in 1977. Wilwood designs and manufactures disc brake systems alongside calipers, fittings, master cylinders, rotors, brake lines and valves. Its street-performance, motorsport and specialized ranges require component selection around the demands of the complete assembly.

Fitment & Compatibility

Verify the right-side layout and seven-eighths-inch handlebar diameter for the intended equipment. The exact page lists a banjo-type M10 x 1 connection and 1/4-32 threaded switch interface, but FL55 identifies an inverted-double-flare connection and bayonet switch for this part. Confirm the actual supplied version; matching the thread pitch alone is insufficient.
