If you spend any time visiting Thailand or Vietnam, you will see scooters and small-displacement motorbikes absolutely everywhere. Many of them (though by no means all) are already Hondas; you'll see Waves and Scoopys in abundance; many of which are 110s.
For city life in particular, little bikes like these are pretty nearly unrivaled. Traffic congestion is so serious that even if you had the money to spend on a larger bike, there wouldn't be much point. In fact, it might almost be as frustrating as having a 4WD and snow tires in winter weather on roads where absolutely no one seems to be able to cope with winter driving in a competent way.
It's all about having the right tool for the situation, you know?
