Team Losi Promoto-MX Aluminum Front Wheel Hub Hex by JAZRIDER JR-LMX02-BK  [JR-LMX02-BK]

Front wheel hub hex for Promoto‑MX

This is an RC-scale aluminum front wheel hub hex intended for use with the Team Losi Promoto‑MX motorcycle dirt bike chassis, supplied as part-type JR-LMX02-BK by JAZRIDER. The piece functions as the interface between the wheel and axle assembly, providing a six-sided drive contact for wheel retention and removal during routine maintenance.

Installation and fit are straightforward for model builders familiar with Promoto‑MX wheel assemblies; use the correct size hex driver and inspect the wheel bearing seating during assembly. The hub hex supports quick wheel swaps and helps maintain consistent wheel alignment when replacing tires or checking suspension settings.

For tuning and maintenance the component plays a supporting role: it stabilizes wheel mounting, reduces play at the hub interface when correctly installed, and simplifies repeatable wheel installation during setup changes. Routine checks for thread engagement and tightness are recommended after track sessions.
