Brembo RMC GP Master Cylinder

Brembo RMC GP Radial Master Cylinder 19x18
Grand Prix Performance

The Brembo RMC GP radial master cylinder represents the technological pinnacle of hydraulic brake actuation for high-performance motorcycles. Directly derived from extensive R&D developments for international top-tier racing series such as MotoGP and WorldSBK, this advanced performance component delivers an unparalleled level of feedback, linearity, and thermal stability under extreme, continuous loads on the racetrack.

Manufactured using a sophisticated CNC-milling process from a single block of high-tensile billet aluminum, the cylinder housing features an outstanding stiffness-to-weight ratio. This extreme structural rigidity ensures a completely lossless transfer of manual force into hydraulic pressure. Pressure point migration (fading) is effectively eliminated, even under the harshest conditions, such as those encountered in the FIM Endurance World Championship (EWC).

Features
- Precision Lever Mechanics (19x18): The combination of a 19 mm master piston and an 18 mm pivot distance provides crystal-clear feedback during hard braking maneuvers, as well as highly precise modulation while cornering.
- Crash-Tested Folding Lever: The integrated folding lever mechanism significantly reduces the risk of a premature failure of the braking system in the event of a lowside or crash.
- Ergonomic Fine-Tuning: Utilizing a race-proven 90° remote adjuster linkage, the lever distance can be micrometrically adjusted even while riding via an optional remote adjuster cable.
- Data Logging Interface: The housing features predefined mounting points to accommodate an LVDT stroke sensor. This allows for seamless integration into professional data acquisition systems to analyze lever travel and brake pressure.
- Wear-Resistant Hard-Anodized Finish: The specialized hard-anodization provides permanent protection against mechanical wear, extreme heat exposure, and aggressive contact with brake fluids.

Q&A
What makes the RMC GP master cylinder different from standard brake systems?
The RMC billet GP master cylinder is machined from billet and incorporates MotoGP-derived technologies for superior precision, braking power, and heat resistance. It offers exceptional modulation and a direct connection between lever input and braking response, ideal for racing conditions.

Is the RMC GP master cylinder suitable for street use?
While technically possible, the RMC billet GP master cylinder is designed specifically for track performance. Its characteristics, such as extreme sensitivity, aggressive braking power, and race-focused ergonomics, are optimized for circuit use and may not be ideal for everyday riding.

What are the main benefits of billet machining?
Billet machining allows for extremely precise tolerances, resulting in a lightweight yet strong master cylinder. This improves durability, aesthetics, and overall braking efficiency, giving riders an unparalleled level of control and confidence.

Is the Brembo RMC GP master cylinder suitable for all motorcycles?
The Brembo RMC GP master cylinder is designed to be compatible with a wide range of motorcycles, including Japanese and European maxisport bikes, custom bikes, Café Racers, and motard bikes. It can be easily installed to replace and improve the original braking system.

Note

Delivery occurs without an external brake fluid reservoir, brackets, or accessory lines.

The Brembo Check app combined with the QR Code is another step in the fight against counterfeiting and will gradually replace the card. At this time both the new Brembo Check app and the anti-counterfeit card can be used to check that products are genuine.
