LOSI Promoto-MX Compatible Rear Brake Caliper Aluminum (Purple) JR-LMX06-PU by Jazrider  [JR-LMX06-PU]

Precision aluminum rear caliper suited to Promoto-MX

This aluminium rear caliper is provided as an RC-scale replacement part for the Promoto-MX motorcycle series. The purple anodised coating provides a distinctive look while the aluminum construction aims to offer a stable mount point for the brake components on model motocross bikes.

Intended role: replace a fatigued or damaged rear brake unit or fit this caliper while experimenting with small brake setup variations. It supports simple mechanical adjustments such as pad positioning and lever travel without impacting the chassis layout.

Installation notes: the design targets direct fitment with Promoto-MX rear brake mounts per the product name. Prefer original mounting screws where applicable and inspect thread engagement and torque settings after initial runs. Conduct brake bedding and low-speed functional checks on a secure surface before full-speed use.

Compatibility and caution: this article is an RC accessory for Promoto-MX motorcycle models only. Confirm compatibility with your particular model before installing and do not apply to full-size vehicles.
