Q. What is the function of kill switch in Ntorq

Usually Kill Switch helps in Stop/Go Traffic or short halts which saves your fuel without spending time to repeatedly switching ignition ON/OFF by key. Its close to throttle so its easy to turn engine ON/OFF without ON/OFF the electricals of the scooter.

One more thing if you only use the kill switch, the drl will always turn on draining the battery, so its wiser to use the key if not only for a short time.If you still want to use it, then you can turn on the headlight switch and the drl will goes dim.

To turn off the engine, thats all, but you have to slow down like in all other cvt scooters to let the engine at idle and only then you can use it.
