This very common master cylinder with 12mm piston was used on most Japanese dirt/enduro bikes until perhaps 2000 or so. It will provide much better stopping power than the Lockheed, Brembo or Grimeca units installed on seventies-era British and Italian motorcycles. Condition is new and perfect!! Comes complete with all internals, brake lever and clamp screws, and has a 10mm threading for a mirror. You will need your own 10mm banjo bolt for the brake line. It is suitable for single disc applications only!!
Included is matching clutch lever with removable, snap-in ignition cutout wiring as shown.
