Brembo offers a wide range of radial pumps and adjustable levers to replace and improve the original plant. Brembo High Performance brake pumps are built with cutting-edge procedures and processes, ensuring operation and excellent performance. Derived directly from the racing world, the Brembo master cylinders are available in two versions, "Radial" and "Radial RCS", easily applicable to all popular Japanese and European motorcycle maxisportive.

RCS radial
Brembo RCS radial brake master cylinder allows you to choose a powerful braking and modulated depending on road conditions, weather conditions, of its sensitivity, the feeling that you have with the bike. It is a patented pump, directly derived from that used in MotoGP, which thanks to the innovative control system allows you to adapt the same master cylinder to different uses of customers, even the most demanding.

Born with the specific intent to transfer the technology Moto GP and Superbike to the general public of enthusiasts, Brembo RCS radial master cylinder is, in terms of technical content and style, a new frontier in the field of high-performance brake components.

The RCS system consists of a registry with which you can change the distance of the lever 18 or 20 mm, so as to achieve the perfect feeling between rider and machine: by varying the distance, in fact, you can make the brakes more responsive and ready (int. 20) or more flexible control (int. 18).

The configuration change is very rapid: just adjust the wheelbase of the pump by turning 180 degrees with a screwdriver on the adjustment device on the front of the guide lever, the cam system (red on 18 mm, black on the 20 mm): hence a different distribution of the braking force without changing its raw power.

The piston seals and the cap of the RCS pumps are the same pumps used by almost all the MotoGP riders and SB, characterized by reduced manufacturing tolerances and excellent smoothness. The lever, however, is made up of two main components: the racing lever and the lever itself, folding and manufactured by forging.

The RCS radial master cylinder is available in two versions: 19 or 15. These numbers indicate the diameter of the piston and determine their use: the 19RCS must be used on two disks brake systems but not 4-piston floating, while the 15 RCS can be mounted on implants Single disc with 4-piston caliper, or twin-plate, but is floating calipers.

For use with two disks brake systems and 4-piston calipers

Please note: You will also need to purchase a Brembo RCS Brake reservoir kit; That is unless you have a way to make a custom reservoir fit onto the master cylinder!
