Images of 16mm RCS Clutch Master Cylinder Shown for Reference

High technology but also attractive and functional. Brembo is also sensitive to the aesthetic aspect of our products as well as the motorcycles that use them. In fact, this radial clutch master was conceived in combination with the RCS brake master cylinder.

Aesthetics and convenience. In fact, the brake master cylinder has the RCS adjustment system (patented by Brembo) for the lever centre distance (18-20) which makes it suited for any type of hand.

The system allows an ideal feeling between rider and bike to be achieved: in just a few seconds using a simple screwdriver you can go from 16 mm for those who want a softer and more comfortable grip to 18 mm for those who prefer a decidedly more Racing feeling on their bike.

The brake master cylinder uses a 17 mm diameter piston, and has a long folding lever (LL). For the surface finishing oxidation was chosen which is normally used in MotoGP and Superbike.

Brembo uses only cutting-edge procedures in order to guarantee excellent operation and performance. In fact, the aluminium alloy master cylinder main body is obtained through forging and is then machined with numerically controlled equipment.


  • Material: Forged aluminium
  • Piston mm: 17
  • Lever ratio: 17mm x 16mm adjustable to 17mm x 18mm
  • Type: RADIAL
  • Surface protection: Hard anodized
  • Weight (gr): 350

Items required to complete installation:

  • We suggest using the Brembo Clutch Reservoir Mounting Kit (Brembo Part# 110.A263.86) as it includes a reservoir, bracket, hardware and tubing.
  • The RCS includes a single banjo bolt with 2 copper washers.
  • If you intend to use your stock reservoir you will require a length of 6mm Tygon 2375 Tubing and 2 3/8" Spring Clamps.
  • Brake fluid will be needed. We suggest replacing all of the fluid in the system when you install the master.
  • The Speed Bleeder Bag and Hose Kit is a real asset when bleeding the brakes. It can keeps the job clean and can be reused.
