Description
BREMBO – GP4-RS Forged Radial Monoblock Calipers, Includes Pads (108mm Spacing)
Brembo part number: 220C78310
They are 108mm spaced so will fit most Japanese bikes.
The radial GP4-RS Monoblock caliper is the latest addition to the Brembo Monoblock caliper range. Each caliper is machined from a single piece of alloy to ensure excellent rigidity under stress in order to deliver powerful, precise and consistent braking performance.
Along with these calipers a different master cylinder is required, that’s why Brembo has introduced the 17RCS. The 17RCS is designed by Brembo to suit calipers with a piston diameter of 32mm or less. You can still run a 19RCS although it is more beneficial and recommended to use the 17RCS with these and the M50 calipers
