Engineered for Track Dominance: The Brembo GP4-PR Left Front Brake Caliper

The Brembo GP4-PR is the pinnacle of racing brake technology, designed for riders who demand uncompromising stopping power and precision on the track. This front left caliper is a true Billet Monobloc unit, meticulously CNC-machined from a single block of high-grade aluminum alloy. This manufacturing process guarantees an unparalleled stiffness-to-weight ratio, ensuring zero flex and consistent, repeatable braking performance under the most extreme racing conditions. It features four differentiated-diameter titanium pistons (32mm and 36mm). This advanced hydraulic configuration is designed to ensure a more efficient and even pressure distribution across the brake pad surface, maximizing braking torque and modulation. The caliper boasts a stunning and functional Nickel Surface Treatment, a finish directly derived from Brembo's experience in MotoGP and World Superbike (SBK). This coating not only provides exceptional resistance to corrosion and wear but also refines the manufacturing tolerances for ultimate performance and a high-tech racing aesthetic. With a 108mm radial mounting distance (Japanese standard) and a specific 21mm offset, the GP4-PR is optimized for racing setups utilizing a narrow band (30mm) brake disc. Please Note: This caliper is designed exclusively for racing use, requires racing-specific discs, and is not compatible with ABS systems. Brake pads (e.g., Brembo Z04) are sold separately.

Best Uses

1. Professional and Amateur Motorcycle Racing: Ideal for competitive circuit use, including SBK, Superstock, and high-level track days where ABS is deactivated.
2. High-Performance Track Bikes: Perfect upgrade for superbikes requiring the ultimate in braking performance, feel, and durability.
3. Specific Racing Configurations: Must be paired with racing brake discs with a narrow 30mm braking band and a 1.5mm spacer to correct the 21mm offset relative to the standard 22.5mm offset on 108mm applications.

Features

1. Billet Monobloc Construction: CNC-machined from a single block of aluminum billet for maximum rigidity and an optimal mass-to-stiffness ratio.
2. Differentiated Titanium Pistons (P4 32/36mm): Four lightweight titanium pistons with varying diameters ensure highly efficient hydraulic pressure distribution and enhanced pad wear consistency.
3. Nickel Surface Treatment: MotoGP/SBK derived finish that provides exceptional corrosion resistance, superior wear properties, and tightened manufacturing tolerances for ultimate precision.
4. 108mm Radial Mount with 21mm Offset: Standard racing mount fitment with a precise 21mm offset for use with narrow brake track racing discs.
5. Triple Bridge Design: An enhanced central bridge structure significantly increases caliper body stiffness, crucial for stable and consistent performance under extreme heat and pressure.

Benefits

1. Uncompromising Braking Power: Achieves superior stopping power and bite thanks to the rigid monobloc body and large-diameter pistons.
2. Exceptional Lever Feel & Modulation: The high stiffness reduces caliper flex, giving the rider an immediate, predictable, and precise feel at the brake lever for perfect control.
3. Maximum Fade Resistance: The use of lightweight Titanium for the pistons and the caliper's race-proven thermal management ensures consistent performance even during long, demanding race sessions.
4. Reduced Unsprung Mass: The billet aluminum and titanium pistons contribute to a significantly lower weight (630g without pads), improving handling and suspension response.
5. Factory Racing Aesthetic: The distinct Nickel plating gives your bike the undeniable, authentic look of a factory race machine.
