The Brembo radial master cylinder with 6 different brake modulation options. The 15RCS CORSA CORTA is characterized by the possibility it provides the rider to adapt the braking "bite point" to the desired riding feeling, in addition to the RCS (Ratio Click System), introduced 10 years ago on the Brembo 19RCS radial brake master cylinder, which allows the center distance of the master cylinder to be adjusted to "18" or "20". The meticulous study to improve the master cylinder has allowed Brembo to propose three brake master cylinders in one and to further improve braking system performance. Furthermore, taking advantage of the mixture stemming from the 18 to 20 center distance and the three maps - R,S,N - no less than 6 different combinations can be attained. The play selector lets the rider choose between the three different available feeling maps. With the Normal map, the bite point position is such to guarantee a more gradual initial phase and is therefore suitable for city riding or braking in poor grip conditions.
