Promoto-MX Front Hub Hex Compatible with LOSI JR-LMX02-GD by Jazrider  [JR-LMX02-GD]

Compatibility notes for Promoto-MX

This aluminium front wheel hub hex is a direct-fit replacement designed for LOSI Promoto-MX style motorcycle chassis, listed as model JR-LMX02-GD. It provides the hex-shaped interface between wheel and axle that Promoto-MX layouts use for wheel retention.

The golden anodized coating signals aluminium construction and offers improved surface resistance versus stock plastic parts. As a precision-machined upgrade, it replaces softer hexes to simplify wheel servicing and strengthen the front wheel mounting area.

Installation notes: remove the wheel assembly using your model’s procedure, take out the old hex, and install the aluminium unit in the same orientation. Confirm axle clearance and refit retaining hardware to the same specification your Promoto-MX requires. Check wheel spin and bearing alignment before operation.

Compatibility advice: verify your Promoto-MX uses the hex pattern shown and that axle diameters match before purchase. This part keeps mounting geometry consistent without altering axle or suspension settings.
