Aftermarket rear hub hex for Promoto-MX

This aluminum rear wheel hub hex fits Team Losi Promoto-MX motorcycle chassis as a direct-fit upgrade. Precision machining and the gold finish produce a firmer contact between wheel and axle than stock plastic hexes, which helps to preserve wheel alignment under load.

Fitting is done by removing the original hex, sliding this hub into place on the axle mating surface, and fastening with the existing wheel-retaining screw. Confirm the hub seats flush against the wheel hub and that bearings or collars remain correctly located before final torque.

Used during tuning and maintenance to reduce wheel-interface flex, the hub gives a harder wearing surface for repeated wheel changes. Regular inspection of hub seating and the retaining screw will help ensure consistent and safe operation.

How should I maintain the aluminum hub to maximise service life?

Clean the hub and mating surfaces after runs, check for burrs or damage, and ensure the retaining screw remains tight but not over-torqued.

Is this hub suitable for competitive use?

Yes — the stiffer interface and improved wear resistance make it well suited to competitive and frequent-use scenarios, provided fitment to the Promoto-MX interface is confirmed.

What should I inspect after an impact?

After any heavy impact, check the hub for cracks or deformation, verify bearing seating, and confirm the retaining screw has not loosened or damaged the mating surfaces.
