This aluminium steering holder is a scale accessory made for the Team Losi Promoto-MX motorcycle model and sold under the JR-LMX05-BK part designation. It replaces the stock steering mount to strengthen the junction where the steering linkage meets the front forks on the Promoto-MX chassis.
Compared with standard plastic components, the aluminium holder reduces flex at the steering pivot, helping to maintain more consistent geometry during heavy landings and rough track sections. Improved stiffness can make steering inputs feel more direct and predictable when tuning steering throw and servo endpoints.
Fitting the upgrade is simple on Promoto-MX assemblies: remove the original holder, fit the aluminium piece into the steering assembly, align the linkage and stops, and secure with the model's factory screws. After installation, check neutral alignment and full-lock travel to ensure smooth operation.
