Brembo Radial Master Cylinder 19RCS BMW S1000RR (2010-, 2015-)
Part Number: 3271A013A00-01
Brembo radial master cylinder 19RCS, CNC machined from forged Aluminum, piston diameter 19mm, adjustable ratio 18mm or 20mm, threads are M10x1, with racing folding lever.The RCS system consists of an adjuster that sets the brake lever pivot distance to either 18 or 20 mm, for the perfect feedback between rider and machine: setting the pivot distance to 20 mm makes the braking system more reactive and immediate, while a pivot distance of 18 mm makes it more precisely controllable. Changing between the two settings is extremely quick: simply adjust the master cylinder pivot distance by turning the adjuster on the front of the guide lever with cam mechanism by 180° using a screwdriver (red indicates 18 mm, black indicates 20 mm). This changes braking power distribution without modifying the pure power of the system itself.
The piston, gaskets and push rod of RCS master cylinders are exactly the same components as those in the master cylinders used by practically all MotoGP and SBK riders, and are manufactured to extremely fine tolerances and ensure very low friction. The lever consists of two main components: the racing lever guide and the folding, forged lever itself.
