Brembo HPK GP4-RX 100 mm kit for radial calipers
If you are looking for the best braking performance, the Brembo GP4-RX calipers are for you! The body of these calipers is made entirely of billet aluminum and consists of two mechanically connected parts. Thanks to the use of this material, these calipers are actually stiffer than cast aluminum monobloc calipers. The GP4-RX gives you tremendous stopping power and incredible control! This model implements a surface finish borrowed from MotoGP. The aesthetically pleasing nickel plating refines the already minimal machining tolerances for improved performance and operating accuracy.
The features of the Brembo GP4-RX 100 mm kit for radial calipers Please note:
The GP4-RX calipers from Brembo are designed to work best with a Brembo 19 RCS brake pump. These calipers are available in 2 different sizes: 100 mm and 108 mm. As a rule of thumb:
- 100 mm: Suitable for all European motorcycles with radial calipers
- 108 mm: Suitable for all Japanese motorcycles (except Yamaha R1 six-piston motorcycles).
But always check the dimensions of the mounting points on your own motorcycle!
You can also use the Brembo Brake Configurator to determine which products fit your motorcycle. You may also need a Brembo Spacer Kit for calipers to make sure the caliper is aligned correctly. This is usually the case if you have larger diameter brake rotors, but some bikes require spacers/spacers anyway. In this document you can read if and which spacer kit you need: Brembo Spacer Kits for Brake Calipers.
