Machined entirely from billet, the GP4 RX calipers are much lighter than any comparable product and features a mass to stiffness ratio which is unrivaled in its class.
Utilizing four 32mm diameter pistons, the Brembo GP4RX calipers have the renowned power and controllability you'd expect from Brembo calipers.
The GP4-RX caliper's pads slide within the body on special guides, which eliminates the use of the pad pins. Also the GP4-RX is the first ever product to use a surface treatment that has been adapted directly from MotoGP.
To finish off the caliper, it has been nickel plated, which not only creates a very attractive look, but it has also allowed the Brembo engineers to make the machining tolerances even finer, which added the benefits of performance and extremely high operating precision.
