Learn MoreThe RCS master cylinder delivers unmatched control in every riding with absolute confidence, whether navigating city streets or tackling challenging terrains.
For your tuning desires, this master cylinder offers unparalleled control and precision. Featuring a 15mm piston and adjustable lever ratio (16mm-18mm), it allows you to fine-tune the clutch feel to your exact preference. Whether you're on the track or the road.
The patented Ratio Click System (RCS) system allows easy modification of the lever ratio between 16mm (for smoother, more powerful engagement) and 18mm (for quicker, more responsive engagement) by rotating the eccentric drive on the lever. This adjustment provides riders with the ability to switch between a smoother, more powerful lever action or a quicker, more responsive engagement, adapting to different riding conditions or personal preferences.
By incorporating the same inner piston, seals, and push rod technology used in MotoGP and WSBK, the floating piston system significantly reduces friction and enhances control. This design delivers a smooth and responsive feel, allowing the rider to experience a stronger connection to the clutch system.
The control for adjusting the levers distance from the handlebar is precisely aligned with the lever itself. This ensures that, regardless of the adjustment, the press push rod maintains the optimal working angle, reducing friction and maintaining consistent performance, whether the lever is closer or farther from the handlebar.
Constructed from forged aluminum alloy, it combines maximum lightness with good stiffness and strength.
