The JAZRIDER JR-LMX07-RD red aluminium rear brake disc offers Team Losi Promoto-MX owners a reliable way to sharpen rear stopping power. It is produced to match the Promoto-MX mounting points so the swap is clean and dependable.
Aluminium is favoured for rotors because it is light and does not rust, keeping running weight down and resisting the elements. This disc aims to deliver steady braking performance across repeated runs while adding a neat visual upgrade.
Installation requires basic RC tools and uses the existing mounting hardware. The disc is intended as a direct replacement for the Promoto-MX rear rotor and does not need additional adapters.
