0110436250 - 13mm clutch or brake master cylinder rebuild kit - fits all hollow pivot lever type master cylinders such as the 916 style remote master cylinders, the coffin style REC type master cylinders + others. Choose to get the kit only or get the kit plus a proper installation tool for the crush washer thing that holds everything in place (there is no snap ring holding things together as you would expect).
This kit will NOT fit any solid lever pivot bolt type front master cylinder.
NOTE: Most Ducati uses 13mm (some used 12mm) on the clutch MC, Monsters & SS models used 13mm BRAKE only if there is 1 single 4-piston type caliper up front. If there are 2 of the 4-piston type calipers up front then there would be a 16mm MC used..
