Developed with technology derived from MotoGP, it combines lightweight construction, high rigidity and precise hydraulic performance.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003cbr\u003eThe caliper body is entirely CNC-machined from solid aluminium alloy. It is manufactured in two mechanically connected sections and optimised using advanced calculation software to remove excess material while maximising the mass-to-stiffness ratio.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003cbr\u003eA distinctive nickel-plated surface treatment, derived directly from MotoGP technology, provides a premium finish while allowing extremely precise machining tolerances.

Instead of conventional pad retaining pins, the brake pads slide along guides machined directly into the caliper body. This reduces friction and contributes to improved brake feel and modulation.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eCentre distance:\u003c\/strong\u003e 108mm\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eOffset:\u003c\/strong\u003e 22.5mm\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eBrake band:\u003c\/strong\u003e Suitable for discs with a 32–34mm braking surface height\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eCaliper code:\u003c\/strong\u003e 220B01010\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003eThe 108mm mounting specification makes the GP4-RX suitable for a wide range of Japanese supersport and naked motorcycles.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDisc Compatibility\u003c\/strong\u003e\u003cbr\u003eThe calipers can be used with standard OEM discs and are also compatible with high-performance racing discs, including Brembo \u003cstrong\u003eSuperSport\u003c\/strong\u003e and \u003cstrong\u003eT-Drive\u003c\/strong\u003e discs.
