Scooter comparison. Which one has the better specs?

Do not pay attention to the price only the specifications in terms of perfomance.

It's a Yamaha not a Honda

You are comparing apples to oranges. The Zuma since it's a two-stroke, will be easily upgradable should higher speeds be needed in the future. However, such upgrades for the C3 are not readily available for four-stroke 49cc engines-yet.
The good news is both can be derestricted to gain a faster top speed.

I would agree with a previous poster and go with a Kymco... but if you must have a honda, I would go with the C3 for 3 reasons.
1: Its liquid-cooled not forced air. This will make your C3 last longer and hold up better in the summer heat.
2: It is fuel injected and not carbureted.
3: TONS of storage compared to other scooters.

You can also derestrict the C3 in about 15 minutes to do 42 MPH. You may get a couple of MPH more when comparing stock to stock but big whoop when comparing the other 3 items mentioned above.

2009 Zuma will be quicker because it has a 2 stroke, and it will probably be unleaded gas, but on the other hand the 2009 C3 will have a better throttle response, and you wont have to mix the oil with the gas. but to answer your question i would go with the zuma, because it looks better.

Kymco is better than the Honda and the Yamaha's put together and still cheaper.

any Honda is damn hard to beat............good luck
