LOSI Promoto-MX Motorcycle Aluminum Front Wheel Hub Hex by JAZRIDER JR-LMX02-PU  [JR-LMX02-PU]

Front wheel hub hex for Promoto-MX

This is an RC-scale front wheel hub hex designed for the Team Losi Promoto-MX motorcycle platform, finished in purple anodized aluminum and supplied under the JAZRIDER JR-LMX02-PU part code. The component replaces common plastic hexes to offer a firmer wheel interface and improved wear resistance during repeated wheel changes and off-road use.

Installers should confirm compatibility with the Promoto-MX fork output and existing axle hardware before fitting. Typical installation involves removing the wheel, seating the aluminum hex onto the wheel hub or axle end, and securing it with the original retaining screw or nut; no extra tools are included. The alloy construction serves to reduce deformation under load and helps maintain consistent wheel alignment, which can affect handling on loose surfaces.

Tuning-wise, this hub hex is a straightforward hop-up: it stabilizes wheel retention and can make small differences in steering feel by limiting unwanted play at the wheel interface. It is intended for RC hobby use only and does not imply any application to full-size vehicles.
