Yea, used sports bikes... that is a big no-no for me. A lot of the little 600's are ragged to piss from kids learning how to ride a sports bike. And then once they mess them all up by learning and get confotable with them, they rag the piss on them again by rompin on them all the time because they feel the need for a bigger bike. When you settle down with a bike you plan on keeping for a while, get a new one. There not that expensive at all. And BTW, it's not the bike you need to really worry about riding, it's everything else around you. You can know your bike inside and out and be 100% confotable on it, but if you lack the motorcycle experience of the open roads, things will be bad. Riding a motorcycle on public roads and highways is WAY different from driving a car, way more than just the physical apsects.
