If you’re looking for ultimate braking performance, you’re looking for the Brembo GP4-RX brake calipers. The body of these calipers is made entirely from billet aluminium and consists of two mechanically connected pieces. Because of the billet material, these calipers are in fact more rigid than cast aluminium monoblock calipers. The GP4-RX will provide you with massive stopping power and insanely good control and feedback. This model implements a surface finish borrowed from MotoGP. The nickel plating, in addition to giving it a decidedly attractive look, allowed the already strict machining tolerances to be refined, all to the advantage of performance and operating precision. Please note: The Brembo GP4-RX calipers were designed to work best together with a Brembo 19 RCS brake master cylinder. These brake calipers come in two sizes: 100 mm and 108 mm. As a rule of thumb, 100 mm should fit all European brand bikes with radial calipers and the 108 mm should fit all Japanese brand
