Service spare hub hex for Promoto-MX

The JAZRIDER JR-LMX03-PU is a purple anodized aluminum rear wheel hub hex made as an aftermarket service part for the Team Losi Promoto-MX motorcycle platform. It secures the rear wheel to the axle interface and transfers drive torque from the gearbox to the wheel assembly.

To install, remove the wheel and associated axle hardware, swap the hub hex onto the axle spline or wheel adapter, then reassemble. Basic RC tools like the correct hex driver are sufficient; confirm bearing fit and check for unwanted axial movement after fastening.

Using an aluminum hub hex gives a firmer mounting point than softer materials and the purple finish helps with quick part identification during maintenance. Keep this item as a direct service spare when addressing wheel alignment or preparing the bike for riding.

Is this compatible with stock Promoto-MX wheel bearings?

The part is intended for Promoto-MX assemblies; confirm your existing bearing dimensions and wheel adapter match the Promoto-MX specification before installation.

What basic tools do I need to fit the hub hex?

You only need standard RC maintenance tools such as the correct-size hex driver and common hand tools for removing the wheel and axle hardware; inspect bearing seating after fitting.

Should I replace bearings when fitting this hub?

Bearings are not listed with this item. If your bearings show wear or corrosion, replace them during installation; otherwise you can reuse serviceable bearings from the original assembly.
