Upgrade your motorcycle’s front braking system with the Brembo GP4-RB Front Upgrade Brake Caliper Set, part number 220B47330. Designed for riders and builders seeking improved braking performance, this front caliper set combines lightweight billet aluminum construction with Brembo’s proven braking technology. The set includes matching left- and right-side front calipers for a complete installation on compatible applications.
The CNC-machined billet aluminum bodies provide strength, precision, and a refined appearance while helping support consistent operation under demanding riding conditions. A four-piston configuration delivers strong clamping force across the brake pads, helping produce responsive stopping performance and smooth, predictable control. The GP4-RB design is engineered to offer excellent brake feel and modulation, allowing riders to apply braking force with greater confidence during street riding, spirited use, or track-focused applications.
Finished in hard-anodized black, these Brembo calipers provide durable surface protection and a clean performance-oriented look. An integrated brake pad guide system helps maintain proper pad alignment and supports efficient servicing. Before installation, confirm compatibility with your motorcycle, rotor, mounting arrangement, axle configuration, and braking system components. Professional installation is recommended to ensure correct fitment, brake line routing, torque specifications, and complete system function. When properly matched and installed, the Brembo GP4-RB front caliper set provides a focused upgrade for riders looking to improve front-end braking response, control, and consistency.
