Promoto-MX aluminium rear hex upgrade

The component is a drop-in style rear wheel hub hex crafted as an upgrade for the Team Losi Promoto-MX Motorcycle platform. Its machined aluminium construction aims to firm the wheel-to-axle interface for steadier alignment under typical dirt riding stresses.

Installation is designed to be direct: the part engages the Promoto-MX rear hex interface and secures at the bike's original fastener points. During fitting, verify that the wheel is centred and that the axle is fully engaged before final tightening to avoid binding or runout problems.

In practical terms this hub hex is a straightforward tuning part that lowers mechanical slop at the rear, helping make rear-end setup and predictability simpler when working on suspension and traction settings.

What specific Promoto-MX points should I check for fit?

Confirm the hex seating face, axle engagement depth and the existing fastener hole pattern match the Promoto-MX standard. Small variances can affect fitment and should be checked before installation.

Are any seal or retaining parts required when installing?

The part uses the bike's original retainers in most cases. If your setup relies on O-rings or special clips, have those items on hand to ensure the wheel remains secure.

Will this change handling noticeably?

You should notice reduced play at the wheel, which can make rear response more consistent; it is a subtle handling refinement rather than a dramatic change.
