The global version of the Honda PCX is equipped with an idling stop system, which automatically shuts off the engine after a few seconds of idle. This feature is not included on the US/Canada model due to safety concerns, having a kill switch and a parking brake instead. To prevent excessive wear on a separate starter motor, the Honda PCX uses its alternator by supplying power to the stator (see Brushless DC electric motor). As a result, engine start is completely muted. This same technology was released in the new 2018 Honda Goldwing.
Other Honda 125/150 scooters with eSP share a common engine with the Honda PCX
