Promoto-MX Compatible Aluminum Rear Caliper - JR-LMX06-GD by Jazrider  [JR-LMX06-GD]

Aluminum rear caliper for Promoto-MX

This aluminum rear caliper is an RC-scale replacement part designed for use on Team Losi Promoto-MX motorcycles. Finished in a golden color, the component provides a metal alternative to the original rear caliper body, intended for direct fitment to the Promoto-MX rear mounting points.

Material choice and part geometry focus on repeatable mounting and consistent alignment with the rear brake assembly. When swapped into the stock location, the caliper functions as the mechanical interface for the RC model's rear braking components and can be used during setup and tuning to verify caliper alignment and clearance.

Installation notes: this part installs at the standard Promoto-MX rear caliper mount and uses the existing mounting holes and hardware on the model. Verify alignment and pad clearance before initial runs, and check fastener torque after the first few operating cycles.
