Brembo 2021 Honda CBR1000RA ABS/2004-2011 CBR1000RR GP4-RB Brake Caliper - Front Left/Right

Brembo GP4-RB Front Left/Right Brake Caliper for 2004-2011 Honda CBR1000RR & 2021 CBR1000RA ABS

Upgrade your Honda CBR1000RR (04-11) or 2021 CBR1000RA ABS with the CNC-machined Brembo GP4-RB front brake calipers. Experience unmatched track stopping power, precision modularity, and a striking hard-anodized black finish. 

Take your superbike or custom build's braking performance to elite racing standards with the Brembo GP4-RB Radial Front Brake Caliper Set. Engineered to directly replace your stock calipers, this premium system features a 108mm mounting pitch and a 22.5mm offset, making it a perfect bolt-on upgrade for the legendary 2004–2011 Honda CBR1000RR and the 2021 Honda CBR1000RA ABS.

Unlike mass-produced cast calipers, the GP4-RB is meticulously CNC-machined from a single solid billet of aircraft-grade aluminum. This two-piece mechanically connected design yields extreme structural rigidity, eliminating caliper flex even under heavy track-day thermal stress.

Internally, stopping duties are managed by four high-performance aluminum pistons with staggered, differentiated diameters (30mm and 34mm). This staggered arrangement ensures even pressure distribution across the brake pads, delivering incredible modulation, initial bite, and consistent lever feel.

Aesthetically, the calipers boast a stunning, stealthy hard-anodized black finish contrasted by the iconic glossy red Brembo logo hand-painted in bas-relief—perfectly blending raw track performance with premium styling.

Best Uses

1. Track Days & Closed-Course Racing: Optimized to handle extreme track temperatures and repeated heavy braking zones without fading.
2. High-Performance Superbike Upgrades: Ideal for owners of 2004–2011 CBR1000RR and 2021 CBR1000RA ABS looking to drastically improve front-end stopping power and lever feedback.
3. Premium Custom & Café Racer Builds: The striking anodized black and red aesthetic acts as the perfect centerpiece for premium, bespoke motorcycle designs.

 Features

1. CNC Billet Aluminum Construction: Machined from solid aluminum blocks for superior density, strength, and weight savings over cast OE calipers.
2. Differentiated 4-Piston Setup: Uses four 30/34mm aluminum pistons to optimize pad wear, maximize clamping force, and refine lever modulation.
3. Perfect 108mm Fitment: Designed with a 108mm mounting pitch and 22.5mm offset, making it highly compatible with Japanese supersport forks.
4. Hard-Anodized Black Finish: Provides long-lasting wear, corrosion resistance, and a premium aesthetic compared to standard painted finishes.
