Brembo Radial GP4-MS CNC Monoblock Brake Caliper Kit 100mm 220D60010

Engineered to meet the demands of both road certification and circuit performance, the Brembo GP4-MS Radial Monoblock Brake Caliper Kit (100mm) represents one of the most technically advanced braking solutions available for supersport motorcycles. With its CNC-machined monoblock aluminium body, proprietary nickel finish, and road-optimised double-sealed pistons, this kit delivers controlled, progressive stopping power with the reliability that safety-conscious riders require — street legal approval (ABE) in preparation.

Key Features

• CNC-machined from solid aluminium billet in a monoblock configuration — eliminates flex, maximises structural rigidity, and reduces unsprung weight to approximately 670 g per caliper (without pads)
• Nickel finish aids thermal dissipation, protecting seal integrity under repeated hard braking while adding a premium aesthetic
• 4-piston design with four 30 mm pistons delivers precise, even pad contact across the full friction surface for confident, linear brake feel
• Double-sealed pistons optimised for road use — enhanced resistance to contamination and fluid ingress for long-term reliability
• Compatible with DOT 4 and DOT 5.1 brake fluid, ensuring straightforward integration with a wide range of road and track brake systems
• Supplied complete with Brembo 07BB3793 Sinter TT high-performance sintered brake pads — a ready-to-fit package with no additional pad purchase required

Engineering for Road and Track

The GP4-MS sits at the intersection of Brembo's racing programme and road-legal engineering. The monoblock construction — carved from a single aluminium billet rather than bolted halves — provides the caliper body stiffness that circuit riders demand, without the weight penalty of cast alternatives. The 30 mm offset and 100 mm radial bolt spacing ensure a clean, direct fit to the OEM fork legs of a broad range of current supersport platforms, removing the need for intermediate adaptors on compatible models.

The nickel surface treatment is not merely cosmetic. It forms a uniform barrier across the caliper body that assists heat transfer away from the brake fluid, helping to maintain consistent pedal feel during extended track sessions or demanding mountain passes. The double-sealed piston design adds a further layer of durability for riders who accumulate high road mileage between service intervals.
