Brembo presents the latest evolution in the radial master cylinder concept with the launch of the new 19RCS CORSA CORTA. This new radial master brake cylinder features a host of innovations, with many of the technical solutions adopted drawn directly from the master cylinders used in MotoGP.
The most significant achievement is, that the 19RCS CORSA CORTA allows the rider to tailor the “bite point” exactly where they want it, with an easily accessible selector on the top of the master cylinder itself (patent-pending technology). The selector operates a cam mechanism to let the user choose between three different responsiveness settings.
In the Normal setting, indicated on the master cylinder with the letter N, the bite point starts more gradually, making it suitable for city riding or braking in poor grip conditions. In the Sport setting, indicated on the master cylinder with the letter S, the beginning of the bite point is shorter than in the N setting. This setting produces a more dynamic response suitable for sportier riding.
Lastly, in the Race setting, indicated on the master cylinder with the letter R, the position of the cam mechanism shortens the initial stage of the bite point even further to produce the same immediate response of the master cylinders used in MotoGP, letting the rider reach the bite point of the brakes instantaneously. This setting is ideal for use on the race track, where every hundredth of a second shaved off a lap time counts.
By simply changing from one setting to another, the rider can configure the braking response and feel of the bike immediately and predictably.
The new Brembo 19RCS CORSA CORTA also features the RCS (Ratio Click System) system introduced 10 years ago on the Brembo 19RCS radial master cylinder, which lets the rider select a fulcrum-to-piston distance of 18 or 20 mm by simply turning the adjuster screw on the front of the guide lever by 180° with a screwdriver. The system uses a cam (red when set to 18 mm, black when set to 20 mm), which adjusts the distance between the fulcrum point and the contact point with the master cylinder push rod by 2 millimeters: this changes the distribution of the braking force without altering the performance of the system in terms of pure power.
The innovative adjustment system introduced with the new Brembo 19RCS CORSA CORTA radial master cylinder contributes to a sense of total control over the bike byletting the rider tailor braking performance to suit their riding style, the weather and road conditions.
A commitment to product improvement has allowed Brembo to offer three different master cylinders in one and to bring the performance of the braking system as a whole to another level. Combined, the choice of two fulcrum-to-piston measurements (18 and 20 mm) and three bite-point settings (R, S and N) offer a total of six different settings.
