Looking to buy an older used bike. I'm 35,6',200lbs. Used to own a yz80 in my teenage years. Haven't rode since then. I always liked the pep that this bike had. From what I've been reading, the KDX200 seems to be a very well liked bike. I was looking at a 1991 model on ebay. Just wondering what I should expect to pay for this bike. ebay item#120268685473 incase someone wants to check it out.
