The performance of this motor to some extend mimicks that of K11" 250V but has several advantages. It can go to the controller's max voltage of 300-340V, has slightly more power and has the flexibility of series/parallel connections. These qualities make it a good racing choice whereby parallel mode is used for racing while series mode for normal driving.
