LOSI Promoto-MX Scale Rear Brake Rotor JR-LMX07-RD by Jazrider  [JR-LMX07-RD]

Rear brake rotor for Promoto-MX models

Made for Team Losi Promoto-MX motorcycle scale models, this rear brake rotor is supplied under part number JR-LMX07-RD. The component is aluminum with a red finish and is intended as a direct replacement or upgraded rotor for the Promoto-MX rear braking system.

As an RC dirt bike accessory, the rotor is aimed at delivering repeatable braking feel and easy servicing rather than changing motor or drivetrain behavior. It is supplied as a single rear rotor sized to fit Promoto-MX compatible hubs.

Setup guidance: this rotor replaces the stock disc and is compatible with the Promoto-MX hub geometry, enabling riders to refine braking modulation and better manage heat during extended track sessions. Note that this is a model part only.
