Aftermarket rear hub hex for Promoto-MX

The JAZRIDER JR-LMX03-PU is an aluminum rear wheel hub hex offered in purple for the Team Losi Promoto-MX motorcycle series. It locates the rear wheel on the axle spline or adapter and transfers drive load from the gearbox to the wheel.

Fitting requires wheel removal and standard hand tools; slide the hub hex onto the axle spline, reinstall hardware, and confirm bearing seating and axial play. Use the correct hex driver and tighten fasteners appropriately before running the model.

The rigid aluminum profile reduces flex versus softer materials and the anodized finish assists quick part ID during maintenance. Keep this unit as a service spare when repairing or preparing a Promoto-MX for track duty.

Which Promoto-MX parts must I check for fitment?

Confirm the axle spline and wheel adapter on your Promoto-MX match the hub hex interface. Measure bearing and adapter fit before completing installation.

How should I inspect the hub after the first run?

After a short test run recheck fastener tightness, inspect bearing seating for loosening, and look for any abnormal wear at the spline interface.

Do I need to buy any extras to use this part?

The product does not list included bearings or hardware; have your original components on hand or purchase replacements if they show wear.
