I would say that the new Honda sh150i is much much better scooter.
it has a 144cc engine, rear disk brake, same as space as zoomer and click, wind shield, 100/120 front/rear tires.
and about the size as the Click, definitely an awesome scooter for bangkok and even the occasional trips outside the city.

While I'm sure that nobody will argue with you about the Honda SH150i being the better scooter, but the Honda Zoomer-X and the Honda SH150i are intended for complete different target groups.

With the 16” wheels the Honda SH150i is much better on long straight trips than it would be in tight city traffic.

Another sales point is that anybody younger than 18-years old can ride a Honda Zoomer-X, while you need a valid drivers license to ride a Honda SH150i. 110Cc scooters are often used by school kids in rural areas for commuting from home to school...

The design of the Honda Zoomer-X, and the low seat height shows a bit that it's intended for this market.
