The Brembo GP4-RX is a 108mm front brake caliper set with a nickel-coated finish and red lettering. It is built from two mechanically fastened billet pieces and uses four 32mm pistons.
The brake pad guides are machined into the caliper body, so no pad pins are needed. This also reduces weight. The hydraulics and shape were tuned and tested for braking under competitive riding conditions.
The set fits most motorcycles that use 108mm calipers, measured bolt to bolt center length. Check your bike for proper sizing and fitment. The Yamaha R1 (70/7) and R6 require trimming the metal front fork mud guard for clearance and installation.
