This CNC-oriented hub hex is produced as a direct replacement for LOSI PROMOTO-MX 1/4 scale motorcycle wheel positions. Constructed from Aluminum 7075-T6, the component provides a rigid axle-to-wheel interface and is sized to accept the larger inner bearings specified by the part number.
For assembly, confirm axle tolerances and bearing orientation before pressing components. The hex is intended to maintain bearing alignment under torsional and lateral loads; ensure mating surfaces are clean and use recommended interference methods for bearing installation. This item is for scale RC motorcycle applications only.

Use these precision hubs when a durable aluminium replacement is required to accept larger inner bearings and retain accurate wheel alignment on LOSI PROMOTO-MX chassis; verify final fitment on the RTR before service loading.
