Radial Brake Master Cylinder Brembo Racing 19 RCS CORSA CORTA fold-up lever 18-20 ratio

MotoGP riders use master cylinders with calibrated and customized IDLE STROKES: now, with the new RCSCorsa Corta, you can feel like a TOP RIDERS. Through the new adjuster, it is possible to choose the Bite Point (where the lever starts braking) then, the braking feeling.

FULL ADJUSTABLE:

-BITE POINT (IDLE STROKE): Three different Maps, R-S-N, the selector operates a cam mechanism to let the user choose between three different responsiveness settings.
-LEVER POSITION: Click by Click You can adjust the Distance of the Lever from the bar and adapt it to your hand or to your needs.
-RCS (Ratio Click System): 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 new selector operates a cam mechanism to let the user choose between THREE different responsiveness settings:

R “RACE” : 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.
S “SPORT” : the beginning of the bite point is shorter than in the N setting. This setting produces a more dynamic response suitable for sportier riding.
N “NORMAL” : the bite point starts more gradually, making it suitable for braking in poor grip conditions (rain).

Technical features of RCS system:

Adjustable ratio: RCS system

This new patented device allows to modify the pump lever ratio on two values, 18 or 20 mm, by simply rotation of the eccentric drive placed on the front of the lever drive. By the RCS system – Ratio Click System – it is very easy to pass from one configuration to the other one, modifying the lever ratio to adjust it to the different characteristics of the braking system, of the usage and driving, such as, for ex., the wet or dry conditions, asphalt with more or less grip, circuit with strong braking. 

This adjustment is the element missing till now to get the ideal feeling among the rider, the driving style, the bike and the circuit.

 

NB. The red spot on the eccentric drive identifies position 18mm of the lever ratio, while black indicates position 20mm.

Moto GP Piston

Piston, seals and push rod are the same as those used in the official MotoGP and SBK master 

cylinders: very narrow tolerances for the highest precision while braking.

 

Body

Produced in forged aluminium alloy, is partially CNC machined and then finished by hard anodizing process.

 

Lever

It is made by two main components: the lever drive and the “half” folding lever, both produced in forged aluminium with black finishing.

 

Micro-Switch for Rear Brake Light

For road use of the RCS M/C, the body has a dedicated housing for a rear light micro-switch, included in the box.

 

 

 

 

In the reservoir section you can choose the right reservoir (you can use the OEM too if separetd).

 

Fits a M10x1,0 mm bajo adapter (normaly japan bikes has M10x1,25mm one), and Oem axial master cylinder brakes hoses could not fit radial mc, we can supply specific brake hoses or the adapter for standard brake hoses (clich here for find it).
