This aluminum rear caliper is an RC-scale replacement made for Promoto-MX Motorcycle models, listed as JR-LMX06-BK. It is intended as an aftermarket option for rear braking assemblies on Promoto-MX dirt bikes, limited to radio-controlled use.
Aluminum material and caliper geometry focus on a durable, serviceable component that integrates with Promoto-MX rear brake mounts. The caliper provides a stable mounting point for brake pads and linkages and allows straightforward swaps during maintenance or setup changes.
Installation notes: remove the rear wheel and original caliper, transfer any reusable pads or hardware if applicable, mount the caliper to the original mount points, then reassemble and test brake engagement at low throttle. Use the correct-sized hex driver for the mounting fasteners and verify pad clearance before running.
