The Brembo GP4-RB 100mm Billet Two-Piece Radial Front Calipers are a high-performance braking upgrade for European superbikes. CNC-machined from billet aluminum with a two-piece design, the GP4-RB calipers maximize rigidity while shedding weight and improving heat dissipation under racing conditions.
Featuring Brembo’s 30/34mm staggered piston configuration, the GP4-RB delivers a strong initial bite, smooth lever modulation, and fade-free braking even in the most demanding situations. The black anodized finish with the Brembo logo provides a sleek, factory race appearance.
Key Highlights:
- CNC billet aluminum two-piece construction for rigidity and reduced weight
- 30/34mm staggered pistons for balanced braking force and precise control
- Black anodized finish with Brembo logo
