Rear Disc for Promoto-MX (Gold Aluminum)

This RC-scale rear brake disc is designed for the Team Losi Promoto-MX motorcycle platform, finished in gold and machined from aluminum to balance light weight with serviceability. It is offered as a direct replacement hop-up for routine maintenance, visual enhancement, or setup trials where the disc is swapped during repairs.

Compatibility targets Promoto-MX model bikes that use the standard rear disc mounting; the disc fits at the rear hub and secures with the model's existing hub fasteners. Typical installation steps include removing the rear wheel, exchanging the disc, and reassembling while confirming alignment and fastener security before operating.

As part of maintenance workflows this disc acts as a replaceable wear item and an aesthetic upgrade. Keep it on hand to service a Promoto-MX between sessions, to test fit during setup changes, or to restore a bike after component swaps.

How do I install the JR-LMX07-GD on a Promoto-MX?

Remove the rear wheel, unbolt the original disc, fit the new JR-LMX07-GD in the same orientation, and refit using the bike's existing fasteners. Check that the disc runs true and fasteners are snug before testing.

Are there any fit checks to perform after installation?

After reassembly, spin the wheel slowly to confirm concentric alignment and that the disc clears the caliper. Perform a low-speed brake test to verify secure mounting and correct operation.
