Precision rear wheel reinforcement for PROMOTO-MX

This MX0505R reinforcement ring set is CNC-machined from 7075 aluminium to provide a precision aftermarket upgrade for LOSI PROMOTO-MX platforms. The parts are engineered to resist edge deformation and maintain concentric mounting surfaces where lighter materials might distort under repeated torque cycles.

The kit installs as a direct-fit reinforcement for the rear wheel assembly, using supplied fasteners to retain original alignment and clearances. By increasing local rigidity at the hub interface, the rings reduce repeatable play and contribute to more consistent setup measurements during tuning and maintenance.

As a focused upgrade component, these rings do not change suspension geometry or drive ratios; they are intended to enhance structural integrity at wheel mounting points, improving repeatable performance for competitive or precision hobby use.

Compatible Models

  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06002

A precision, material-led upgrade for PROMOTO-MX owners who require firmer hub mounting surfaces for repeatable setup and improved long-term wear resistance.

What tolerances are critical when fitting these rings?

Ensure the hub face and fastener seats are clean and free of burrs; the rings rely on true seating to maintain concentricity and prevent preload on bearings.

Are torque settings important for the supplied fasteners?

Yes, use consistent torque on the supplied screws to avoid distorting the ring or hub. Hand-tight then torque to the vehicle maker's small fastener spec is recommended.

How does 7075 aluminium compare to other alloys here?

7075 offers a higher strength-to-weight ratio and better fatigue resistance than common stamped alloys, providing a durable reinforcement without large weight penalties.

Is any surface prep needed after installation?

Inspect fastener torque after initial runs and check for any signs of fretting; light anti-seize on threads can help in long-term service environments.
