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

Aluminium Front Hex for Promoto-MX Bikes

This component is an RC-scale front wheel hub hex produced for the Team Losi Promoto-MX motorcycle chassis, finished in purple anodized aluminum and distributed under the JAZRIDER JR-LMX02-PU part code. It replaces softer plastic hexes to give a more positive wheel seating and better longevity through frequent wheel swaps and rough terrain riding.

Installers should check fork output dimensions and the existing axle fastener before fitting. Standard fitment involves removing the wheel, sliding the alloy hex onto the wheel hub or axle end, and fastening it with the original screw or nut; no additional hardware is included. The stiffer alloy reduces flex under load, helping to preserve alignment and predictable wheel behavior on uneven surfaces.

From a tuning standpoint, the JR-LMX02-PU is a modest, effective upgrade: it tightens the wheel interface and can refine steering feedback by eliminating play at the connection point. This item is for hobby RC use only and not for real-vehicle application.
