Brembo RCS Clutch Master Cylinder

The Brembo RCS Clutch Master Cylinders bring to the table a level of consistent clutch feel and performance that is unsurpassed in the motorcycle racing world. They are also a great addition to pair with a Brembo Brake Master Cylinder to complete the set. Brembo offers many piston size options to accommodate all displacements of motorcycles, from 250cc supermotos to 1300cc+ speed machines and everything in between.

The Brembo RCS Clutch Master Cylinders allow for riders to choose between speed or more precision to best complement their riding style, track/street conditions and other clutch components. The unique design of the RCS system offers the flexibility to change the clutch lever ratio at the turn of a screw. The 20/18mm setting provides an extremely quick and effortless action and the 18/16mm setting allows for better feel and modulation.

Additionally, the Brembo lever features an adjustable thumb screw that can be customized to fit a range of riders’ hands. In the event of a crash the outer portion of the lever folds up and away to avoid damage. The patented master cylinder is constructed of forged aluminum and then CNC machined down to remove any excess weight. All of its components, including the piston, seals and pushrod, are the same as those used in MotoGP and WSBK.

Brembo offers a wide range of radial master cylinders and adjustable levers to replace and enhance an original system. Brembo High Performance master cylinders are manufactured with state-of-the-art processes to ensure outstanding function and performance. Derived directly from motorsports, Brembo master cylinders are available as "Radial" and "Radial RCS" variants, which are easily installed on the most popular Japanese and European hypersports models.

Brembo RCS (Ratio Click System) radial brake master cylinders allow the rider to choose between power or precision in relation to road conditions, the weather, personal preference for feel and familiarity with the bike. This patented master cylinder, derived directly from the unit used in MotoGP, features an innovative adjustment system that allows the same master cylinder to cater for the many different requirements of even the most exacting customer.

Created specifically to bring MotoGP and Superbike technology to countless enthusiasts, the Brembo RCS radial master cylinder sets new standards for high performance brake components in terms of technology and style.

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 and 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.
