This machined aluminium hub hex is a direct replacement for the front and rear wheel positions on LOSI PROMOTO-MX 1/4 scale motorcycles. Built from Aluminum 7075-T6, the part provides the axle-to-wheel interface and accommodates the larger inner bearings shown in the part listing.
When fitted the hub keeps bearing alignment and secures the wheel under riding loads; verify axle clearance and how you will secure the wheel on your PROMOTO-MX chassis before completing the job. The kit supplies wheel hubs, bearing positioning columns and the bearings listed in the packing block, so check bearing orientation and mating surfaces during fitment. This product is made for RC motorcycle use only and is not intended for full-size vehicles.
