{"product_id":"gp4-rx-radial-brake-caliper-set","title":"GP4 RX Radial Brake Caliper Set","description":"The Brembo GP4 RX is a set of high-performance radial brake calipers designed for superior stopping power and control. Each caliper features a body precision-machined from two billet CNC aluminum parts, finished with a nickel coating—a treatment derived from MotoGP technology that provides an attractive aesthetic and optimized manufacturing tolerances. These calipers are equipped with four 32mm diameter pistons, contributing to their enhanced performance.\n\nSintered brake pads are included and pre-installed. The kit also contains an instruction handbook and Brembo decals. These calipers are perfectly interchangeable with standard Brembo Street radial calipers. However, Brembo strongly recommends that this caliper not be installed if the motorcycle's OEM brake system includes ABS, or that the ABS system be deactivated prior to installation. This is because ABS systems are calibrated for specific brake fluid volumes, and these aftermarket calipers may have different fluid volumes, potentially affecting ABS performance. A minimum master cylinder diameter of 18mm is recommended, with examples like the Brembo 19x16 or 19x18 or 19RCS being suitable.\n\nIt is important to note that mounting screws are not included, and most applications require a specific mounting kit. Additionally, while some users have reported success with ABS systems after tuning, Brembo does not guarantee ABS functionality with these non-OEM calipers due to differences in piston size and brake fluid volume. For certain motorcycles, like the Honda XADV, specific disc thickness requirements may prevent installation without modifications to brake lines or the master cylinder.","brand":"Brembo","offers":[{"title":"Default Title","offer_id":52687280013624,"sku":"220B01020","price":1549.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660682729.jpg?v=1784882167","url":"https:\/\/store.motormia.co\/products\/gp4-rx-radial-brake-caliper-set","provider":"MOTORMIA","version":"1.0","type":"link"}
