LOSI Promoto-MX Rear Hex Precision Hub JR-LMX03-BK by Jazrider  [JR-LMX03-BK]

High-strength rear hex for Promoto-MX motorcycles

This rear wheel hub hex is offered as a precision replacement for the Team Losi Promoto-MX Motorcycle platform. The machined aluminium design emphasises a tighter wheel mount to reduce flex and keep alignment stable during regular off-road operation.

Fitting is intended to be direct: the unit locates to the Promoto-MX rear hex interface and fastens using the bike's existing mounting points. Ensure the axle is correctly seated and the wheel is centred before final clamping to preserve smooth rotation and avoid binding.

As an upgrade part it targets reduction of rear mechanical slop, which helps deliver more repeatable alignment and clearer feedback when adjusting rear suspension and traction settings.
