if the payment is piss cheap and you enjoy it keep it. I have sold shit when my savings dropped, but when it drops i always find a way to get it back up. Prioritize what your spending your money on and go from there. It's always cheaper to ride than to drive a car. And if you're pushing your limits practice some more by yourself. Or who cares if your at the back of the pack. At least your out! With that all being said. I do have a buddy looking to sell his bike for like $700-800. I dont remember what it is, a 650 something.
