Cycle Cat BM series radial brake caliper adapters are designed to adapt forks having standard bottom configurations to facilitate the use of radial brake calipers. The OBM-1 kit is intended specifically for use with the Ohlins R&T forks, and Ducati superbike models prior to the 749 and 999. Designed and built of solid billet aircraft grade aluminum, and machined for both maximum strength and rigidity consistent with minimal weight, the OBM-1s are an outstanding, bolt-up kit complete with all required fasteners. Radial brake calipers are not included. Because the brake caliper select for use by the rider determines the configuration of hydraulic lines, hydraulic lines are not inluded with the OBM-1 kit. The OBM-1 is available in either stock black or silver anodized finishes. Custom finishes are available on special request.
