RCS Corsacorta RR Radial Brake Master Cylinder

The Brembo RCS Corsacorta RR (110E71110) is a high-performance radial brake master cylinder, engineered as the next evolution of racing-inspired braking systems. Machined from billet, its design has been refined for a lighter weight and a closer resemblance to components used in top-tier motorcycle racing. The hard oxidation finish, in a titanium grey hue, provides exceptional wear resistance and minimizes friction between moving parts, while the float and seals are directly sourced from MotoGP. This master cylinder offers extensive adjustability. The lever ratio can be switched between 18mm (for enhanced modularity) and 20mm (for maximum braking readiness) via the Ratio Click System (RCS). Furthermore, the bite point, or the point at which the lever begins to apply braking force, can be precisely tailored through a three-position selector (R-S-N). The 'R' (Race) setting offers an immediate response akin to MotoGP master cylinders, the 'S' (Sport) setting provides a more dynamic feel, and the 'N' (Normal) setting offers a gradual engagement suitable for varied grip conditions. It is crucial to note specific compatibility and installation considerations. The 19RCS Corsa Corta RR is designed for twin-disk setups with axial or radial calipers and is intended for expert riders. It is explicitly stated as not compatible with Floating Calipers. Additionally, while some related clutch levers are available for specific BMW models, they may not be compatible with features like Shift Assistant Pro or double switch clutch levers, and replacement levers may require sending the unit back to the factory for replacement.
