BRAKING RM4 – rotating master cylinder The BRAKING RM4, derived from the acronym for Rotating Master Cylinder 4, represents the latest development in BRAKING brake technology. These braking systems are designed for maximum efficiency and user-friendliness without compromising on design and aesthetics. Main features of the RM4: Precise ergonomics: The brake fluid reservoir of the master cylinder can be rotated by up to 180°, allowing it to be customised to the preferences of each rider. In addition, the pump elements for the right and left side are interchangeable, which increases flexibility and adaptability. Maximum performance: The innovative 4-piston brake caliper, which consists of two separate parts, ensures outstanding and consistent braking performance. This design ensures even power distribution and increases stability during intensive use. Racing look: The aggressive and dynamic design inspired by the world of motorbike racing, which was already appreciated on the F.I.R.S.T. model, is also present on the RM4. This striking appearance gives the braking system a professional and sporty character. These technical features make the BRAKING RM4 a first-class choice for drivers looking for both performance and aesthetics in their braking system.
