...street legal dirt bike...
I have no idea. I just need a big one. And it would have to be something I can ride on the street.
That looks like a mini bike. I realize that's your chosen topic, but I had in mind a full sized dirt-street bike. I'm nearly 6'4", I want something I'd feel comfortable on.
The only real bike is a monkey with nice power and takegava parts.
I own 2 monkeys with now 125ccm , a Honda dax and a monkey clone from jingchen.
