21-013   Radial master cylinder, Custom
<< Back 

Now you can experience the improved "feel", that comes with a radial master cylinder, on your custom bike. The 21-013 series can be ordered with a 14 mm or 17.5 mm diameter cylinder, depending on what calipers it is set up with on your bike.

This clean looking item, with integrated reservoir, comes as either a brake (-OA) or clutch (-OB) master cylinder.

Combine it with our handlebar clamp electronic switch assemblies (73-100) for a clean looking handlebar on your custom bike.
