GP4-MS radial brake caliper kit, the monoblock evolution of the GP4 series.
Unlike the GP4-RX model (which is in two pieces), the GP4-MS is the first Brembo monoblock caliper machined from solid (CNC) available for street use, directly transferring MotoGP technology to production motorcycles.
Monoblock Construction: Made from a single block of aluminum, it offers superior rigidity and less deformation at high temperatures.
Ventilation Fins: Features integrated fins on the caliper body for more efficient heat dissipation, a design derived from MotoGP prototypes.
Dust Seals: Includes a double seal (internal and external) that allows prolonged street use without the frequent maintenance required by track-only calipers.
Technical Features:
Center Distance: 100 mm (European Standard).
Pistons: 4 aluminum pistons with a diameter of 30 mm.
Finish: MotoGP surface nickel plating.
Offset: 30 mm.
Recommended Pump: It is recommended to pair with a 17 mm radial pump (e.g., Brembo 17RCS).
Vehicle Compatibility
The 100mm center distance is ideal for:
Aprilia: RSV4 and Tuono V4 (all versions), RS 660.
BMW: S 1000 RR (all years), M 1000 RR/R, S 1000 XR.
Ducati: Panigale V4/V2, Streetfighter V4, Monster 1200.
KTM: Super Duke 1290/1390 R.
