Overview

The BBR Motorsports Rear Brake Rotor Adapter is a billet-machined adapter designed to convert an old BBR KLX110 Disc Brake Hub to fit CR80/85/CRF150R rotors. It features an anodized silver finish and is made from 6061-T6 aluminum.

This adapter allows the use of the BBR Works Style 190mm Rotor or other 190mm CR80/85/CRF150R rotors. Combined with a Nissin caliper mount, it enables the conversion of an old BBR KLX110 rear disc brake to use a CR/CRF Nissin caliper.
Show original supplier description
The BBR Motorsports Rear Brake Rotor Adapter is a precision-engineered component designed for BBR KLX110 models, enabling an upgrade to a 190mm rear brake rotor. This adapter bridges the gap between older BBR Disc Brake Hubs and the larger rotor sizes found on CR80/85 and CRF150R models, including BBR's own Works Style Rotor. Constructed from durable 6061-T6 aluminum, the adapter features an anodized silver finish for corrosion resistance and a clean aesthetic. Its primary function is to facilitate the use of 190mm rotors, which can significantly enhance braking performance. When paired with a compatible Nissin caliper mount, this adapter allows for the integration of a more powerful CR/CRF Nissin caliper, offering improved stopping power and control. This adapter is confirmed to fit BBR Production Bikes MM12P models from 2010 to the present. It is a key component for those looking to update their existing BBR rear disc brake system with newer, higher-performance parts.
