Rear wheel hex in precision aluminium for Promoto-MX

This rear wheel hub hex is designed as an aftermarket replacement for the Team Losi Promoto-MX Motorcycle chassis. Machined from aluminum, the component focuses on a firmer wheel-to-axle connection to help minimise unwanted movement and maintain alignment during everyday off-road use.

Fitting is straightforward: the hex mates to the Promoto-MX rear interface and fastens to the existing points on the model. Check wheel centring and ensure the axle engages fully before tightening to preserve runout and prevent binding.

As a tuning item it offers a simple way to reduce rear mechanical slack, which makes setup adjustments more predictable when dialling in rear-end behaviour at the track.

Can I fit this to other motorcycle kits besides Promoto-MX?

It is made with the Promoto-MX rear hex interface in mind. If another kit shares identical hex geometry and screw pattern it may fit, but always compare dimensions and mounting points first.

Will I need to modify the bike to install it?

No major modification should be required for a matching Promoto-MX; the part uses the model's existing fastener positions. Light trimming is only needed if your specific chassis differs from standard Promoto-MX specs.

How does the alloy hex affect wear and maintenance?

Aluminum reduces elastic deformation compared with soft plastics, so you should see less gradual play. Inspect the hub and axle engagement periodically for wear and retighten fasteners to spec.
