{"product_id":"gp4-rx-nickel-plated-radial-brake-caliper-set","title":"GP4-RX Nickel Plated Radial Brake Caliper Set","description":"The Brembo GP4-RX is a high-performance radial brake caliper set designed for demanding motorcycle applications. Each caliper body is meticulously CNC-machined from billet aluminum, featuring a two-piece construction for enhanced rigidity and performance. The nickel-plated finish, mirroring that found in MotoGP, not only provides an attractive aesthetic but also optimizes manufacturing tolerances for superior accuracy.\n\nThis kit includes four 32mm diameter aluminum pistons, designed to deliver significant braking power and modulation. Sintered brake pads are pre-installed and included, along with an instruction handbook and Brembo decals. The calipers are interchangeable with OE radial calipers featuring a 108mm mounting distance, though spacers and bolts may be required depending on the specific application. Brembo recommends a minimum master cylinder diameter of 18mm, suggesting models like the 19x16, 19x18, or 19RCS for optimal performance.\n\nInstallation requires careful consideration regarding existing brake systems. Brembo advises against installing these calipers on motorcycles equipped with ABS systems, or to deactivate the ABS system if present, due to potential hydraulic conflicts. Specific notes for models like the Honda CBR 1000 RR, CBR 600 RR, and CB 1000R indicate that 310mm stock discs may not be compatible, often requiring 320mm discs and specific adapter part numbers (e.g., 105998709) for proper fitment. Similarly, applications on Kawasaki Z1000 and Yamaha R1 models may necessitate adapter kits (e.g., 220A02421 for Z1000, 220A06115 for R1 2015) and replacement brake lines. The calipers are confirmed not to fit motorcycles with axial calipers, such as the 2008 Yamaha FZ1S ABS.","brand":"Brembo","offers":[{"title":"Default Title","offer_id":52687280243000,"sku":"220B01010","price":1289.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662156621.jpg?v=1784882168","url":"https:\/\/store.motormia.co\/products\/gp4-rx-nickel-plated-radial-brake-caliper-set","provider":"MOTORMIA","version":"1.0","type":"link"}
