Thats rad man. I want a 300 so bad,but my chick is lame and wont throw a leg over. I mean seriously she wants to be a back pack.
I rode the wife's little Ninja for one short ride at the Dragon Trip last year. The trick is definitely keeping it in the right gear and rpm's, otherwise you'll dog it out and lose speed. But yeah, just wring it's neck and throw it around. You can't beat the bang for buck fun factor of these little things.A 250 would surely teach maintaining momentum, not to mention the much lower operating costs.
And you get to wring the thing's neck, EVERY ride.
