This aluminum rear brake disc is produced for Team Losi Promoto-MX scale motorcycle models and is identified as JR-LMX07-BK. It is intended as a direct fit replacement for model brake systems only.
In function the disc replaces the rear rotor and gives a secure surface for the brake pads to act on. Confirm your motorcycle model matches the Promoto-MX configuration to ensure correct installation.
To install, remove the wheel and old rotor, transfer any spacers or necessary hardware, mount the new disc, and check pad clearance and alignment. After assembly, perform a low-speed bench test to ensure brakes engage smoothly before returning the model to full operation.
Tuning notes: integrating this disc into a braking setup can affect pad life and bite; inspect fasteners regularly and replace the disc if you spot excessive wear or warping. Treat the black surface with mild cleaning methods to avoid degrading the finish.
