Brembo 15RCS CORSA CORTA Radiale Master Cylinder is the 19RCS Evolution, the 15RCS with BITE POINT Adjustment.

MotoGP riders use master cylinders with calibrated and customized IDLE STROKES: now, with the new 15RCS Corsa Corta, you can do the same.
Through the new adjuster, it is possible to choose theBite Point (where the lever starts braking) then, the braking feeling.

15 RCS Corsa Corta is full adjustable:

1. 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.
2. 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.
3. 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 real lever stroke is given by the total lever stroke less the idle stroke; the idle stroke is the piston stroke from the lever rest position to the brake liquid inlet hole.

Usually this parameter, depends on the various tolerances, product type or model.

The most significant achievement is, that the 15RCS 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.

The 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).

Bite Point is the new feauture, that is added to the two existing setting options:

• Lever Position (Distance from bar) Adjustment
• RCS (Ratio Click System): This 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.
  The red spot on the eccentric drive identifies position 18mm of the lever ratio, while black indicates position 20mm.
  

Other Features:

Brake lever
The lever is made of two main components: the racing lever drive and the lever itself, folding and manufactured by forging. In the lever joint it has been inserted a patented system which allows the rotation only by the effect of an eventual tumble of the bike, without the possibility of an accidental rotation and getting in this way a bigger dynamic
safety.
The control for the lever distance adjustment from the handlebar has been re-placed and now it is in axis with the lever itself, guaranteeing the assembly of the eventual remote adjuster.
By using this control, the press push rod does not move in respect to the master cylinder body, keeping the best working angle of the push rod. Therefore, either by getting the brake lever closer or farer to the handlebar, the efficiency of the kinematics motion does not change, assuring less friction and lack of scattered forces.
In addition the lever has its fulcrum on the pump body by mean of a bushing/gauged pin system which guarantees high stiffness and better feeling together with a high resistance to wear.

Micro-switch
A special housing has been designed for the rear stop light mechanic micro switch, for street usage of the master cylinder. The micro-switch is supplied in the same master cylinder package.
The switch works "normally open" when the lever rests; by pressing the lever it closes the circuit. The switch can not replace a switch that works "normally closed", such as BMW switches, Yamaha equipped with cruise control (ex MT-10 and Tracer)

19RCS , 17RCS, 15RCS, 14RCS ? These numbers identify piston diameter:

• 19RCS Corsa Corta to be installed on twin disks bikes with axial or radial calipers, for expert rider level. Not compatible with Floating Calipers
• 19RCS to be installed on twin disks bikes with axial or radial calipers, for all rider levels. Not compatible with Floating Calipers
• 17RCS Corsa Corta to be installed on twin disks bikes with axial or radial calipers whose pistons diameter is 32mm or lower, for example Ducati Panigale or RSV4, Yamaha R6 etc etc , for expert rider level. Not compatible with Floating Calipers
• 17RCS to be installed on twin disks bikes with axial or radial calipers whose pistons diameter is 32mm or lower, for example Ducati Panigale or RSV4, Yamaha R6 etc etc., for all rider levels. Not compatible with Floating Calipers
• 15RCS Corsa Corta to be used on twin disks braking system carrying floating calipers (Naked), and on single disk bikes (motard).
  The 15 RCS with 15 x 20 set up works like a 16 x 18 mc, while 15 x 18 equals a 16 x 16 mc.
• 15RCS to be used on twin disks braking system carrying floating calipers (Naked), and on single disk bikes (motard).
  The 15 RCS with 15 x 20 set up works like a 16 x 18 mc, while 15 x 18 equals a 16 x 16 mc.
• 14RCS to be installed on single/twin disks Scooters and single disks Motorcycles (from 50cc up to 600cc) . Available both Right and Left Side.

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

Please Note : To better describe the product we use images of the master cylinders 15 / 17 / 19 without distinction, the master cylinders are in fact all the same externally except for the printed number 15 / 17 / 19, the one that identifies the diameter.
