It's a great bike, easy to ride, not too heavy, and all that. If you did a lot of freeway riding, you would want something a little bigger, but around town, or for a weekend cruise on country roads, you could hardly do better.
But if you're thinking about your first bike, you don't want to go out and buy a shiny new one. You're going to be hard on your first bike. You may well drop it once or twice before you get the hang of it, and you will probably abuse the clutch. I would say your best bet is to get a 5-10 year old bike to learn one, maybe even one with a few scrapes and bruises. After six months or a year you can sell it for about what you paid for it, and by then you will know better what you want.
