LOSI Promoto-MX Steering Mount Upgrade for Precision Tuning - JR-LMX05-PU by Jazrider  [JR-LMX05-PU]

Precision-focused aluminum steering mount for Promoto-MX

This machined aluminum steering holder is an RC-scale replacement part for the Team Losi Promoto-MX motorcycle chassis, offered as model JR-LMX05-PU. It is designed to replace the stock steering mount and give a firmer, more wear-resistant interface between the steering assembly and front fork on Promoto-MX dirt bike models.

Specifically for Promoto-MX motorcycles, the component is an accessible hop-up for pilots seeking a metal mounting point instead of the plastic original. It contributes to consistent alignment under repeated steering actions and helps when dialing in steering throw and centring during setup.

Installation follows the original screw pattern. Remove the stock holder, align the aluminium piece with the steering shaft and fork tabs, use the existing hex screws and check there is free rotation at the steering link and servo horn. Minimal additional parts are required for standard Promoto-MX chassis fitment.

For tuning checks, verify steering centring after installation, confirm no binding at full lock, and resecure fasteners after a short bedding-in period. The part is for RC dirt bike use only and does not change servo, ESC, or motor specifications.
