The last time I looked at magazine fuel consumption figures automatic scooters were shockingly poor – a car could do better. I think it’s down to the continuously variable transmission.
Maybe that does not bother you but if it does and you don’t want a full manual then see if you can find a Honda stepthrough with semi-automatic transmission. With these the rider decides when to change gear and the clutch is operated automatically when you use the gear lever. Driven hard my old stepthrough still gives over 120 mpg which a scooter won’t, apparently, get near.
Later models are, I think, a full 125 and have telescopic front forks so you can actually use the front brake hard without locking the wheel.
A pal does work on Chinese branded scooters and, based on his experience, I wouldn’t give one house room.
