LOSI Promoto-MX Front Wheel Hub Hex by JAZRIDER JR-LMX02-GD  [JR-LMX02-GD]

Front wheel hub hex for Promoto-MX

This aluminum front wheel hub hex is an RC-scale replacement part intended for Team Losi Promoto-MX style motorcycles, supplied by JAZRIDER under model JR-LMX02-GD. The component acts as the interface between the wheel and axle, matching the hex-style wheel retention used on Promoto-MX chassis layouts.

The golden anodized finish identifies the aluminum material and helps resist surface wear in routine use. As a machined hop-up part, it is intended to replace stock plastic hexes or older metal hexes to simplify wheel changes and long-term durability of the front wheel mounting area.

Installation notes: remove the wheel assembly per your model's standard procedure, slide out the existing hex, and fit the aluminum hex in the same orientation. Verify axle clearance and secure any retaining hardware to the same torque or fitment specified by your Promoto-MX setup. After installation, check wheel spin and bearing alignment before running.

Tuning role: swapping to an aluminum hub hex can improve repeatability of wheel positioning and ease maintenance during setup changes, particularly when you frequently swap tires or service bearings. Use this part when you want consistent mounting geometry without altering axle or suspension settings.
