LOSI Promoto-MX Motorcycle Aluminum Steering Holder by JAZRIDER JR-LMX05-PU  [JR-LMX05-PU]

Aluminum steering holder for Promoto-MX

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

Designed specifically for Promoto-MX motorcycles, the holder is a straightforward hop-up for pilots who want a metal mounting point in place of the original plastic piece. It helps maintain alignment under repeated steering inputs and when fine-tuning steering throw or centring behaviour during setup sessions.

Installation is direct and uses the same screw points as the original part. Remove the stock steering holder, align the aluminum piece with the steering shaft and fork tabs, install the existing hex screws and verify free rotation of the steering link and servo horn. Minimal trimming or additional parts are required when used on Promoto-MX chassis as supplied.

For tuning, check steering centring after fitting, confirm there is no binding throughout full lock, and retighten hardware after a short run-in. The part is intended for RC dirt bike use only and does not alter electrical components such as the servo, ESC, or motor.
