Brembo Radial RCS Brake Master Cylinder for 1" Handlebars

Description

The Brembo RCS radial brake master cylinder offers a choice between powerful or adjustable braking, depending on road conditions, the weather, personal preferences, and driving sensations. Thanks to its innovative adjustment system, this patented brake master cylinder (derived directly from MotoGP versions) means that the same brake master cylinder can be adapted to different and highly demanding driver applications. Developed with the precise intention of transferring MotoGP and Superbike technology to the wider audience of enthusiasts, the Brembo RCS radial master cylinder, in terms of technical content and style, is a new frontier for high-performance brake components.
The RCS system comprises a locator whereby it is possible to change the lever ratio to 18 or 20 mm to set the ideal “feeling” between rider and bike. By changing the ratio, the brakes can be made more responsive and faster (20 mm) or more modular (18 mm). The change of configuration is very quick: with the eccentric system (red on 18
mm, black on 20 mm), a simple screwdriver can adjust the lever ratio by turning the locator on the front guide lever by 180°. This gives rise to a different distribution of braking force that does not affect raw power. The small piston, seals, and cap of RCS master cylinders are the same as for the master cylinders used by almost all MotoGP and Superbike riders, characterized by very tight machining tolerances and optimal smoothness.
The RCS radial master cylinder is available in two versions: 19 mm or 15 mm diameter piston. The 19RCS must be used on twin disc systems with
4 non-floating small pistons, while the 15RCS can be mounted on single-disc units with a 4-piston caliper, or twin-disc with floating calipers. On-road use of the brake master
cylinder is enabled by a specific microswitch for illuminating the Stop Light (brake).
