Precision-engineered rear motor flange (disk side) machined from high-strength aluminum to restore axial alignment of the motor-hub and disc assembly on Dualtron electric scooter rear drives. The part provides a tight bearing seat and machined mounting faces to preserve rotor runout and brake disc concentricity for reliable braking performance on Achilleus, Achilleus 35Ah and Thunder 1 variants. Surface finishes control corrosion and mating tolerance while maintaining the correct bolt pattern for direct replacement. Suitable for service-level repairs where precise hub spacing and disc alignment are required on select Dualtron electric scooter platforms including Ultra and Ultra 2 Up.
