The Zuma 125 looks good to me. I just bought a used Vino 125 and am enjoying riding it; I could see picking up the bigger Zuma in a couple of years. For local riding, the 125cc size seems like kind of a sweet spot -- more get up and go than the 50cc scooters, but without the weight and cost of the big ones.
I'm not sure who is the market for the big scoots, but it isn't me -- I like the little ones because they are cheap and small and fun to ride around town. For long distance and fast speeds, call me traditional but I'd rather be on a motorcycle. Is their appeal mostly that they have automatic transmissions? (Anyone remember those CB750s with auto transmissions from the 1970s? Maybe they were just a few decades before their time...)
