LOSI Promoto-MX Rear Wheel Aluminum Hub Hex by JAZRIDER JR-LMX03-GR  [JR-LMX03-GR]

Rear wheel hex hub for Promoto-MX

This aluminum rear wheel hub hex is a scale RC replacement part designed for Team Losi Promoto-MX motorcycles. Finished in green, the component serves as the interface between the rear wheel and the drive assembly on Promoto-MX chassis layouts used in 1/..? scale Promoto-MX models.

Installation is straightforward for an RC technician familiar with Promoto-MX wheel assemblies: remove the wheel from the axle, swap the existing hex with this aluminum unit, and secure using the original wheel nuts and fasteners. The part is intended to work with factory-style wheel mounting hardware and standard hex drivers.

In a tuning context the hub hex provides a rigid mounting surface for the rear wheel and is suitable as a direct replacement piece during maintenance or minor setup changes. Use it when replacing worn plastic hexes or when you need a color-matched spare for chassis upkeep on Promoto-MX motorcycles.
