I'm looking to buy a KDX 220.
I'd like to know what do I have to look for if I set my goal on a used bike ?
I have a few dirt bikes and the kdx would be for my son. He started riding on a TY 250 a couple years ago and now he is on an IT 175 1982. I'd like to get him a newer machine with better brakes, suspension etc. Naturally I'm also thinking about the grin it will put on my face when I'll be the one riding it

Also if I decide to gat a new one , what would be a good price ?
I live in Quebec and this bike is very popular here.
