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

Billet-style rear caliper for Promoto-MX models

This aluminum rear caliper is supplied as an RC-scale replacement part for the Promoto-MX motorcycle line. The purple anodized finish makes the unit easy to identify while the aluminum body gives a firmer mounting platform for the brake system on model off-road bikes.

Intended role: fit this caliper when replacing a worn or damaged rear brake assembly or when evaluating small brake adjustments. It allows basic mechanical tuning like pad alignment and lever travel tweaks without changing chassis geometry.

Installation notes: this component is engineered for direct fit to Promoto-MX rear brake mounts as stated in the product name. Reuse the original mounting hardware where practical and verify thread engagement and fastener torque after the first run. Perform bedding and low-speed brake checks on a safe surface before normal operation.

Compatibility and caution: this item is an RC-scale accessory for Promoto-MX motorcycle models only. Confirm fitment against your bike before installing and never install on full-size vehicles.
