State-of-the-art technology for racing performance.

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.

The 15 RCS may be installed in single or dual disc systems with 4-piston floating calipers.

  • Switchable between 18 mm and 20 mm ratios.
  • Master cylinder body: Forged aluminium then subsequently CNC worked.
  • MotoGP floating piston.
  • Two lever components: Racing lever guide and the folding, forged lever.
  • Micro-switch: A special housing to accept a micro brake light switch making this radial master cylinder suitable for road use.
  • Lever contrast springs.
  • Lever span adjustable.
  • Remote reservoir design (if you do not have a Brembo reservoir you will need to fit one as well as reservoir pipe and pipe clips).
  • Integral bleed nipple for rapid bleeding after assembly / service.
  • This item will fit: Universal - most current sportbikes with 7/8" bars or clip-ons, designed to be used with 1 four-piston caliper or 2 two-piston calipers.

Yes, this should work just fine. Unfortunately, Honda has phased out the front brake master cylinder for your bike.

What is no 15 stands for?
I just bought 2013 Kawasaki Zx14R and would like to change the master cylinder like this brembo unit. but I would like it to be the same lenght as my stock lever. could you kindly advise Thanks George

The 15 stands for the size of the piston in the piston in the master cylinder. The 15 wont be powerful enough for the calipers on the ZX-14 and you would want to run the RCS19. I don't have the exact specifications on the levers but the Brembo lever is basically standard length lever and will not be a much different length than the stock lever. I have attached a photo of an RCS19 mounted on a ZX. Please keep in mind you will need to purchase a 10x1.00 banjo bolt for this master cylinder also.

2013 Canam Spyder RSS?
Will this work with the RSS as the Spyder has all brakes controlled by a single foot brake.. I know in the only one I've seen for sale it has to tie into the brake cylinder to be able to operate Thanks Richard

I am sure this can be made to work in that application but it will not be a direct bolt on. Installation will also vary depending on whether you are trying to have this just control the front brakes or if you would like it to operate all the brakes. You would need to also wire in a brake switch on this so it would activate the brake light when using this versus the foot brake.
