Upgraded rear hex for Promoto-MX performance

This aluminum rear wheel hub hex is a direct-fit accessory for Team Losi Promoto-MX motorcycle chassis. Precision machining and the gold finish create a firmer contact between wheel and axle versus common plastic hexes, which helps preserve alignment during demanding runs.

To fit: remove the original hex, position the aluminum hub on the axle mating face, then secure using the existing wheel-retaining fastener. Make sure the hub seats evenly against the wheel hub and that bearings or collars remain correctly located before final tightening.

In a tuning context the part reduces flex at the wheel interface and supplies a robust wear surface for repeated wheel swaps. Regular inspection of seating and the retention screw will keep track performance predictable.

Will this hub change handling or feel on the Promoto-MX?

The stiffer wheel interface can reduce small amounts of flex, which often translates to more predictable cornering and steadier wheel alignment under load.

Does the added aluminum weight affect balance?

The hub adds minimal mass at the wheel; any balance change is usually negligible but you can re-check wheel runout after fitting to be sure.

Should I change wheel mounting or tightening technique?

Use the same retaining hardware and tighten evenly; avoid over-torquing and verify the hub seats fully to prevent lifting or misalignment.
