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

Scale rear brake disc for Promoto-MX chassis

This rear brake disc is intended for Team Losi Promoto-MX motorcycle scale models and is identified by part number JR-LMX07-RD. The item is manufactured from aluminum with a red finish and serves as a direct replacement or optional upgrade for the Promoto-MX rear braking assembly.

For RC dirt bike applications the disc is focused on reliable braking response and routine service compatibility, not on altering drivetrain or motor outputs. It is provided as a single rear disc for installation on Promoto-MX compatible hubs.

Fit and tuning: the replacement disc installs into the existing Promoto-MX rear hub layout and gives modelers a simple way to adjust rear brake feel and reduce thermal stress during prolonged use. This is strictly a model component.
