I presume this is scoot you are refering to:
http://www.cfmoto.cn/product/moto/v3-3.asp
firstly, it is a scooter, not a motorcycle. What is the difference? This one has a CVT (automatic) transmission. There is more to it than that, but as a starter bike that is really all you should care about.
What this means is that when you move up to a ZZR 600 (or whatever your next bike is) you won’t have trained your brain and body to shift gears properly. Lots of people learn on scooters, but they rarely jump from a scooter to a sport bike. It is usually to something more relaxed…
Comments specific to this scoot:
It has a listed top speed of 100km/h (60 mph). That is much slower than any of the bikes you listed. My ZZR-250 (engine of a ninja 250) happily plays at speeds above 130km/h. Personally, I would not take any bike that can’t do 115km/h on a freeway or interstate.
So, will it be a better tourer than the Ninja 250? Nope.
Does it get better fuel economy? Yes, but just barely. The difference in cost between running that scoot and a ninja 250 would be dollars a month.
There appears to be a number of reviews/comments about the scoot on the net. I haven’t had a chance to read any of them, so I really don’t know what is being said about it. But I am very skeptical about bikes made in China. China’s motorcycle industry is not even close to the quality of Korea, let alone any of the big bike companies.
You may spend more time fixing that scoot than riding it.
Lastly, do NOT get a ZZR-600 as a starting bike. I know it is not as hardcore as a current ZX-6R, but it is still a very hardcore bike. The ZZR-600 is simply last gen’s ZX-6 with a more comfortable seat adn higher bars. Seriously, it is not a friendly bike to start out on. It has every vice and danger of any other 600cc super-sport.
Too boot, it is not a comfortable bike. I’m 6′ and it has my knees bent pretty hard. My ZZR-250 is a much much more comfortable bike.
Ninja 250, Ninja 500, GS500 – all are good choices.
The CF Moto V3… can’t do freeways, won’t teach you clutch control and shifting, and you roll your dice for quality.
The ZZR-600, make it your second bike.
