I found a used '05 WR 450 in Cycle Trader and talked the guy into $5,000 (Honestly, because it's all I have). Supposedly, it's in excellent condition, and the guy seems trustworthy, but I've only talked to him on the phone. There aren't too many ads out there for these bikes, so it's hard to guage the value. Am I getting a good deal, or should I keep looking? Please help fast, the deal is going down soon!
