Rear Hub Hex (Aluminum) for LOSI Promoto-MX JR-LMX03-GR by Jazrider  [JR-LMX03-GR]

Rear hub hex for Promoto-MX bikes

This aluminum rear wheel hub hex is produced as a scale RC replacement for Team Losi Promoto-MX motorcycles. The green finish and precise face geometry let it serve as the mechanical interface between the rear wheel and the drive assembly on Promoto-MX chassis variants used in 1/..? scale Promoto-MX models.

To install: remove the wheel from the axle, replace the old hex with this aluminum version, and secure the wheel back using the original nuts and fasteners. The component is made to work with factory-style wheel mounting hardware and standard hex tools.

For tuning and setup the stiffer aluminum surface gives a consistent mounting point for the rear wheel, useful when making minor adjustments or swapping worn parts during maintenance cycles.
