The S40 is a 650 single with cruiser looks, light handling, plenty of custom options. Pretty big following. It's not'a 250 cc but, you can shop around for insurance and I bet you can find a decent rate.
thanks for the suggestion. it looks a little too cruiser-y for me but maybe i'm just getting worked up over what image i want the bike to be. kind of reminds me of a rebel and virago. i think i still prefer the tu250's body.
