This aluminium steering holder is a scale accessory made for the Team Losi Promoto-MX motorcycle model and identified by the JR-LMX05-BK part designation. It is intended as a direct replacement for the factory steering mount to increase rigidity where the steering linkage connects to the front forks of the Promoto-MX chassis.
As an aftermarket upgrade, the aluminium construction reduces pivot flex versus common plastic parts, helping steering geometry stay more consistent during jumps and rough surfaces. That steadiness can make small steering and servo endpoint adjustments translate into more predictable handling on varied terrain.
Installation is carried out like the original Promoto-MX assembly: remove the stock holder, fit the aluminium item into the steering assembly, align linkages and stops, then secure with the original fixings. After installation, verify neutral steering alignment and test full-lock travel for any binding.
