The new GP 4RX, directly derived from GP 4RR, caliper is directly interchangeable on the forks of the most popular Japanese supersport bikes and will mount with OEM rotors, as well as with Brembo HP Rotors (as used by New World Supersport Champion - Cal Crutchlow) and the brand new Brembo T-Drive Rotors. The sliding action of the brake pads is enabled by special guides machined directly in the body of the caliper, and accordingly, the GP 4RX has no guide pins. Particular care has gone into the design of the hydraulics, which utilize four pistons of 32 mm diameter to ensure that the renowned attributes of power and operational flexibility associated with every Brembo caliper are suitably maximized. Supplied as a kit, the caliper comes with sintered pads — technologically - the top option on today’s market, also with full instructions, Brembo stickers and special thermo tapes as used on competition machines to monitor the operating temperature of calipers, as befits the unmistakable racing profile of the product.
