Promoto-MX Front Wheel Hub Hex Upgrade for Team Losi - JR-LMX02-PU by Jazrider  [JR-LMX02-PU]

Front Hex Details and Fitment

This is a scaled RC front wheel hub hex intended for the Team Losi Promoto-MX motorcycle platform, presented in purple anodized aluminum and listed under the JAZRIDER JR-LMX02-PU part code. It replaces standard plastic hexes to provide a firmer engagement at the wheel and improved resistance to repetitive wear during competitive or backyard off-road sessions.

Prior to fitting, ensure the Promoto-MX fork output and axle fastener are compatible. Typical installation steps include removing the wheel, seating the aluminium hex on the hub or axle end, and securing it with the original screw or nut; extra tools or hardware are not supplied. The alloy body helps keep the wheel interface true under load, which supports consistent steering characteristics.

In tuning terms, this hop-up tightens wheel retention and can subtly affect steering feel by removing unwanted movement at the interface. Intended solely for RC hobby use, it is not suitable for full-size vehicles.
