LOSI Promoto-MX Steering Holder Upgrade - JR-LMX05-PU by Jazrider  [JR-LMX05-PU]

Machined aluminum steering mount for Promoto-MX

This aluminum steering holder is an RC-scale replacement part for the Team Losi Promoto-MX motorcycle chassis, supplied as model JR-LMX05-PU. It replaces the stock plastic steering mount to deliver a more rigid, wear-resistant interface between the steering assembly and the front fork on dirt bike Promoto-MX setups.

Made for Promoto-MX motorcycles, the part is a simple hop-up for pilots wanting a metal mounting point in place of the factory plastic piece. It helps maintain alignment under repeated steering inputs and when fine-tuning steering throw or centring during setup sessions.

Installation is direct and uses the same screw points as the original holder. Remove the stock steering mount, align the aluminum piece with the steering shaft and fork tabs, fit the existing hex screws and verify free rotation of the steering link and servo horn. Minimal trimming or extra hardware is usually required on supplied Promoto-MX chassis.

For setup checks, confirm steering centring after fitting, ensure there is no binding through full lock, and retorque hardware after a short run-in. The component is intended for RC dirt bike use only and does not alter electrical parts such as the servo, ESC, or motor.
