MotoGP Technology for the Street & Track

The GP4-RS caliper was engineered using Brembo’s exclusive cast monobloc manufacturing technology, allowing the caliper body to be formed from a single piece of aluminum for maximum structural rigidity and reduced weight. Compared to the already legendary Brembo M4 monobloc, the GP4-RS is approximately 10% lighter while offering increased stiffness and superior braking response.

Its aggressive racing-derived architecture improves braking consistency during hard use while minimizing flex under extreme hydraulic pressure. The result is sharper lever feel, improved modulation, and enhanced rider confidence during heavy braking zones.

Advanced MotoGP Cooling System

One of the defining features of the GP4-RS is its patented MotoGP-derived piston cooling fin system. The integrated fins surrounding the pistons increase airflow exposure by approximately 30%, dramatically improving heat dissipation in one of the most thermally stressed areas of the braking system.

Benefits Include:

• Reduced brake fluid temperatures
• Improved fade resistance
• More consistent lever feel
• Increased pad longevity
• Better performance during extended track sessions

The included Brembo thermotape temperature strips allow riders to monitor caliper operating temperatures exactly like professional race teams.

Race-Level Braking Precision

The compact hydraulic system utilizes four lightweight 30mm aluminum pistons designed to maximize stopping power while maintaining precise braking modulation. The GP4-RS delivers an extremely direct and progressive brake feel, allowing riders to confidently trail brake deeper into corners and maintain better control under aggressive braking loads.

The GP4-RS is ideal for:

• High performance sportbikes
• Trackday motorcycles
• Race-prepared superbikes
• Canyon riding
• Riders upgrading from OEM radial calipers

For optimal braking performance, Brembo recommends pairing these calipers with a Brembo 17RCS radial brake master cylinder.
