I used to have a 1982 rm125. It was a great bike for me, never let me down....also they were the best bike out in the early 80's and the first water cooled 125cc model. mine had a winseco pisten, dg pipe, and renthal sprockets and it could keep up with the newer 125's easily in the desert!! the only thing i would look out for, is if it still has the stock pisten they have a tendacy to explode. it happened to me and I had to get chunks of pisten out of my crank case....
