Designed for Team Losi Promoto-MX motorcycle models, this rear brake disc carries the part number JR-LMX07-RD. The disc is made from aluminum with a red finish and is offered as a replacement or upgrade for the Promoto-MX rear brake system.
As a model accessory, the disc emphasises consistent braking characteristics and easy maintenance fitment rather than any change to drivetrain or motor performance. It is supplied as a single rear disc to install on Promoto-MX compatible hubs.
Fitting advice: replace the stock rear disc with this unit and use standard hub hardware to secure it, then test and adjust brake modulation to suit your setup. This product is for scale model use only.
