LOSI Promoto-MX Motorcycle Aluminum Rear Caliper by JAZRIDER JR-LMX06-BK  [JR-LMX06-BK]

Aluminum rear caliper for Promoto-MX

This aluminum rear caliper is an RC-scale replacement part made for Promoto-MX Motorcycle models, offered under JAZRIDER part JR-LMX06-BK. It is intended as a direct aftermarket option for rear braking assemblies on Promoto-MX dirt bikes, keeping scope limited to radio-controlled models.

Material choice and geometry focus on a durable, serviceable part that integrates with existing rear brake mounts on Promoto-MX chassis. The caliper's role is to provide a stable mounting point for brake pads and linkages, and to serve as a straightforward swap during maintenance or setup changes.

Installation notes: remove the rear wheel and original caliper, transfer any reusable pads or hardware if applicable, mount the JAZRIDER 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.
