LOSI Promoto-MX Rear Caliper Upgrade (Aluminum, Red) JR-LMX06-RD by Jazrider  [JR-LMX06-RD]

Promoto-MX Rear Braking Unit Overview

This red anodized aluminum rear caliper is an RC-scale replacement designed specifically for LOSI Promoto-MX motorcycle models. It acts as a direct replacement for the rear braking assembly on Promoto-MX chassis and is supplied by JAZRIDER as model JR-LMX06-RD.

Focus is on durability and consistent looks: the aluminum construction keeps mounting rigid for pads and linkages, while the anodized surface helps resist scuffs and grime from frequent dirt use.

Installation and tuning notes: because the caliper matches Promoto-MX rear mounting and brake linkage geometry, installation is usually straightforward with original fasteners. After fitting, confirm pad seating and adjust lever travel gently to match your preferred brake response.

Use cases: ideal as a tougher replacement for stock parts, a spare for competition cycles, or to keep braking feel uniform after chassis modifications; intended for RC dirt motorcycle setups.
