Brembo RCS19  Brake Mastercylinder w/ FOLDING Lever  (RCS 19)   
The revolutionary aspect of the Brembo RCS19 Brake Mastercylinder is the ability to choose between the 19x18 and 19x20 configuration. If you have read about Brembo Master Cylinders, you will know what these numbers mean and that there is a trade-off between the two pivot configurations. Not to say that either configuration is bad, but the rider had to choose between varying degrees of feel and power. Now the rider can change the configuration to suit their needs. No more compromises! 
Another unique aspect to the RCS19 is it comes with a microswitch for the brake. 
For racers, the adjuster knob has been relocated to the same position as the 19x18 Billet Folding Brake Master Cylinder that is used by Valentino Rossi and Nicky Hayden in MotoGP and WorldSuperBike. Two springs have been installed to ensure constant contact between the lever and the pushrod to ensure a longer lifespan. 
The Brembo 19RCS brake master cylinder retains features that made Brembo the top brake system manufacturer today including forged CNC-machined construction and a folding lever that reduces crash damage.

Can be ordered with a short lever. Just message if you want one in place of the long lever
