Brembo 17RCS Radial Clutch Master Cylinder + Reservoir Kit 110A26355 / 110A26386

Brembo 17RCS Clutch Master Cylinder Fold-Up Lever

Brembo Radial Master Cylinder has made the history of the Racing Brake System, the most used MotoGP or SBK master cylinder, and it is the market leader.

Adjustable ratio: RCS systemThe RCS offers flexibility to change the clutch lever ratio at the turn of a screw. This would enable the rider to decide on the 19 x 20 option normally used on the street or the 19 x 18 option suited to track day or amateur racing. This option is achieved by using an eccentric drive, which is turned by the simple screw mechanism and has a colour-coded pivot rod end that allows the rider to understand the current setting at a glance.

Master cylinder body
The master cylinder body is in aluminium alloy, produced by forging and CNC (Computer Numerical Control) machined by lightning milling.
Very closed manufacturing tolerances, similar to those used in MotoGP, guarantee the perfect matching with the floating piston due to a working precision never seen. For the superficial finishing, it has been chosen that the hard anodizing, the electrolytic process converts the surface of the aluminium and its alloys into a very hard oxide coating that guarantees high resistance to abrasion and corrosion.

Clutch lever
The lever has two main components: the racing lever drive and the lever itself, folding and manufactured by forging. In the lever joint, a patented system has been inserted, which allows the rotation only by the effect of an eventual tumble of the bike, without the possibility of an accidental rotation and getting, in this way, a bigger dynamic safety.
The control for the lever distance adjustment from the handlebar has been replaced. Now it is in axis with the lever itself, guaranteeing the assembly of the eventual remote adjuster.
Using this control, the press push rod does not move with respect to the master cylinder body, keeping the best working angle of the push rod. Therefore, either by getting the clutch lever closer or further to the handlebar, the efficiency of the kinematics motion does not change, assuring less friction and a lack of scattered forces.
In addition, the lever has its fulcrum on the pump body by means of a bushing/gauged pin system which guarantees high stiffness and better feeling together with a high resistance to wear.

Switch
This master cylinder is NOT supplied with a switch; if you need this feature, add to your cart Banjo Bolt with Buil-In Pressure Brake Light Switch 10x1.0 mm.

Lever contrast springs
High-load springs have been chosen to guarantee constant contact between the eccentric drive and the push rod; in this way, you can avoid wear due to the knocking by the vibrations of the vehicle, and an item of further safety is introduced in the transient phase between accelerator release and brake, resulting in an advantageous life increase of the various components.

It fits an M10x1.0 mm banjo adapter (typically, japan bikes have an M10x1.25 mm one).
OEM axial master cylinder clutch hose could not fit the radial clutch master cylinder; we can supply a specific line.
