Precision rear hub hex for Promoto-MX

This rear wheel hub hex is manufactured as an aftermarket replacement for the Team Losi Promoto-MX Motorcycle chassis. The machined aluminum construction provides a firmer wheel-to-axle interface to help reduce play and keep alignment consistent under normal RC dirt riding conditions.

Fitting is intended to be direct: the hex locates to the Promoto-MX rear interface and secures with the model's original fastener points. During installation, check wheel centring and axle engagement before final tightening to maintain consistent runout and prevent binding.

Functionally the hub hex is a simple upgrade that reduces mechanical slack at the rear wheel, making alignment tasks and rear-end setup more predictable for tuning work on dirt circuits.

Is the hub hex specified exclusively for Promoto-MX bikes?

It is specified for the Promoto-MX rear hex interface. If your model uses the same geometry and screw pattern it may fit, but confirm measurements to be certain.

Does the package include mounting screws or retainers?

The core listing describes the machined hub hex itself; hardware inclusion is seller dependent. Contact the vendor to confirm if screws or pins are bundled.

What performance gains are typical after fitting this part?

Expect reduced play at the wheel and steadier alignment versus stock plastic hexes, which can assist with predictable rear handling and easier tuning adjustments.
