LOSI Promoto-MX Wheel Hub Hex Precision Mount JR-LMX02-GD by Jazrider  [JR-LMX02-GD]

Wheel mounting precision for Promoto-MX

This machined aluminium front wheel hub hex is an aftermarket replacement for LOSI Promoto-MX style motorcycles, carrying model number JR-LMX02-GD. It is the interface unit that secures the wheel to the axle while matching the hex retention pattern used by Promoto-MX chassis.

The golden anodized finish identifies aluminium construction and offers enhanced surface durability compared to stock plastic parts. As a machined hop-up, it aims to replace softer hexes to make wheel removals quicker and to increase the front-end robustness.

Installation notes: follow your model’s wheel removal steps, remove the existing hex, and install this unit in the same orientation. Check axle clearance and tighten retaining components to the same fitment or torque used on your Promoto-MX. Verify wheel rotation and bearing alignment before track use.

Tuning impact: an aluminium hub hex gives more consistent wheel sit and can speed tyre changes and bearing servicing. Fit this part when you need reliable mounting geometry without altering axle or suspension dimensions.
