This scale rear rotor is intended for use with Team Losi Promoto-MX motorcycle models and is supplied as part number JR-LMX07-RD. The rotor is crafted from aluminum with a red finish, specified as a replacement or upgraded disc for the Promoto-MX rear brake assembly.
Designed for RC dirt bike use, the disc emphasises steady braking response and routine serviceability without impacting drive system characteristics. It ships as a single rear disc for installation on Promoto-MX compatible hubs.
Fitment and setup: the disc installs into the Promoto-MX rear hub layout and can be used by hobbyists to adjust rear braking modulation and reduce heat accumulation during long practice sessions. This item is for model use only.
