This rear rotor is machined from 7075-T6 aluminium as a scale replacement for LOSI 1/4 PROMOTO-MX motorcycles. It offers a direct-fit form factor for routine servicing and light performance tuning while retaining a consistent braking response under normal hobby use.
Fitting is usually done by removing the wheel and replacing the original disc, using the existing screws and mounting points. The rotor pair is sold to match standard rear brake assemblies on the specified PROMOTO-MX models. Use standard RC hand tools and double-check spacing and alignment prior to final torque.
