I had a guy offer me a 79 rm 125 in trade for my 2005 yz 250. Not straight up. He said he wanted $800 for it. I want 2200 for my Yz. Anyhow, i just want to know what his bike is really worth. It looks alright, pipe is good, tank is good, runs well. I'm just lookin for a bike to putt around on. Any idea where to get parts. Any info on this model would be nice. thanks
