I'm getting ready to buy my first dirtbike and from all of my research on the internet, the CR250 looks like the bike for me. I was just curious, are there any model years that I should avoid? Somebody was saying I should avoid 97 to 99 and another was saying 93 or earlier. Any reasons why? There is a TON of CR250's for sale around here in central Oklahoma. Being my first bike, I would rather get a used one. Thanks for any info! Matt
