This aluminum rear brake disc is produced as a direct replacement part for the Team Losi Promoto-MX motorcycle scale model, finished in purple anodize for visual match and corrosion resistance. It is an RC-scale component intended for use on the rear wheel braking system of the Promoto-MX chassis, offering a durable metal alternative to stock plastic discs.
Installation is straightforward for standard Promoto-MX rear hubs: remove the original disc, align the replacement on the hub, and secure using the existing fasteners. No extra tools beyond the model's common hex driver are required, and retainers or spacers already fitted to the hub remain unchanged. Inspect thread engagement and torque to the model manufacturer's recommended levels.
In tuning and maintenance, this aluminum disc is used to stabilise braking feel and reduce wear on the disc surface compared with softer materials. Hobbyists commonly install an anodized metal disc when prioritizing repeatable pedal response during track runs or when replacing a worn original part.
