Upgrade your motorcycle’s front braking system with the Brembo GP4-RB Front Upgrade Brake Caliper Set, part number 220B47340. Designed for riders and builders seeking dependable stopping performance, this front caliper set combines race-inspired engineering with durable construction for consistent operation under demanding conditions. The set includes both front left and right calipers for a balanced installation.
Each Brembo GP4-RB caliper is CNC-machined from billet aluminum to provide a rigid, precise foundation for effective braking. The four-piston design helps distribute clamping force evenly across the brake pads, supporting strong stopping power and predictable response at the lever. Riders benefit from excellent braking feel and modulation, making it easier to control braking input during spirited street riding, track use, or performance-focused motorcycle upgrades.
A hard anodized black finish adds corrosion resistance and a clean, professional appearance while helping the calipers withstand regular exposure to heat, road conditions, and brake dust. An integrated brake pad guide system supports proper pad alignment and smooth operation, contributing to consistent contact and reliable serviceability. The Brembo 220B47340 GP4-RB set is a practical choice for performance applications where braking control, durability, and high-quality component construction are essential. Verify vehicle, fork, rotor, and mounting compatibility before installation, and use appropriate professional procedures when servicing the braking system.
