Brembo Master Cylinder radial PR19 RCS for Harley Davidson Ø25.4 mm

PR19 RCS BREMBO long lever folding radial brake master cylinder for Harley Davidson with Ø25.4 mm tube.

Supplied with double banjo bolt + brake light contact.

The RCS device consists of an eccentric drive that allows the ratio of the master cylinder lever to be selected between 18 and 20 mm, to obtain the ideal feel for the rider depending on his riding style and the motorbike.

By simply selecting the lever ratio, it is now possible to have a more reactive system feel (20 mm) or a more adjustable one (18 mm).

Today, the RCS brake master cylinder is available in two versions: 19 or 15.

These numbers indicate the diameter of the piston and define the application of the master cylinder:

19RCS for double-disc systems with axial or radial mounting of four-piston calipers (Non-floating).

15RCS for single-disc systems (SuperMotard, 125 ...) or double floating two-piston calipers (4 pistons in total).

The range also includes two versions of RCS clutch master cylinder: 19 or 16.

In the case of RCS 19 the ratio can be changed between 18 and 20, in the case of RCS 16 the ratio can be changed between 18 and 16.
