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

Direct-fit aluminium rear caliper for Promoto-MX

This aluminum rear caliper is supplied as an RC-scale replacement part for the Promoto-MX motorcycle line. The purple anodised finish provides visual distinction while the aluminium body is intended to deliver a steady mount for the brake system on model motocross machines.

Intended role: replace a damaged or tired rear brake unit or use this caliper when experimenting with brake setup changes. It supports routine mechanical adjustments such as pad alignment and lever travel modification without altering chassis geometry.

Installation notes: the component is designed for direct compatibility with Promoto-MX rear brake mounts as stated in the product title. Where possible, retain original mounting hardware and check thread engagement and fastener torque following the first run. Carry out brake bedding and functional tests at low speeds on a protected surface before regular use.

Compatibility and caution: this listing describes an RC accessory for Promoto-MX motorcycle models only. Verify fitment for your exact model prior to installation and never use on full-size vehicles.
