I actually prefer the Zenox. But then again, that's almost like saying I prefer Herpes to genital warts.
Seriously though, I can appreciate why some people might like this type of design or riding style. I'm not one to throw cold water on such a statement.
I personally quite liked the riding position of the Venox. I would have bought one when they first came out, but for the price of it, which I considered to be quite high at the time.
The thing I dislike most about either of the two, is the absolute worst grade of chrome imaginable. They rust to pieces before your very eyes, and with no decent chroming facilities in Taiwan, then if you like the shiny look of your Kymco, and want to keep it that way, then you are going to have to keep replacing all those shiny parts after almost each time it rains.
That's the cosmetic element.
The next element is the power, and as mentioned the Hipster is slow, heavy and sluggish. The Venox has a lot more power, but that isn't saying much. It still acts very unresponsively, the rear brake pedal wallows up and down and all over the place, due to its cable routing, making braking more of an art than a skill, and there are other alternatives.
I think these bikes are rare because of the alternatives, when considering new prices. I can't comment on used prices, as they are messy. Largely due to the fact that the condition of used examples varies greatly.
Personally, given the options, I'd be saving longer, and forking out more cash, for a better, Japanese ride over this Taiwanese one.
To put it into my own terms:
I'd look at the Hipster, and then want the Venox. I'd look at the Venox, and immediately want a Honda equivalent. If I bought a Venox, then I wouldn't be miserable, but I'd always know it wasn't great in any one area at all. No-matter what bike I may end up with though, I'd always be thinking "I'm glad I didn't get the Hipster!"
The Hipster isn't great on looks, in my opinion, and indeed in the opinion of most. Just ask some folks here. If it's something you want to go posing on, then the opinions of others really count here.
If it's merely for comfort, and if you find the Hipster a comfortable to ride, then disregard everything I've said entirely. Personal comfort I can't argue with.
If its performance, then I think I don't need to argue the point that a small engine in a heavy bike isn't going to get you anywhere relatively quickly.
There are Hipsters available used. New? Well Kymco aren't listing them in their official site
I'd suspect from just looking around, that they aren't produced for the local market any longer.
