I have been looking for a good deal on used bikes for a while now. I found a 2006 rmz250, and a 2005 crf250r. They both run great, and dont need anything. They are the same price, and are both the same distance away. Which one should I buy, and why? Also are their any things I should watch out for when i go to look at them, or after I get either one? Thanks, Mitchell.
