This aftermarket aluminium hub hex replaces the stock front and rear wheel hubs on LOSI PROMOTO-MX 1/4 scale motorcycles. Fabricated from Aluminum 7075-T6, the hub provides the axle interface and supports the larger inner bearings referenced in the part listing.
Installed correctly the hub maintains bearing alignment and secures the wheel under dynamic loads; confirm axle fit and retention approach on your PROMOTO-MX chassis before completing installation. The kit contains wheel hubs, bearing positioning columns and the specific bearings listed in the packing block, so inspect sealing surfaces and bearing orientation during assembly. Intended for RC motorcycle use only and not for road vehicles.
LOS262012+LOS262013+LOS262014
Ideal when you need a solid aluminium replacement that accepts larger bearings and fits LOSI PROMOTO-MX wheel locations; always trial-fit and check clearances before final torque.
