Owned a couple of bikes 20 years ago and just bought one to play around with at bit. Won't be racing or anything like that just riding around our property a little.
Bike is a 1982 Suzuki RM125. Got it for next to nothing. Only thing I can tell is not stock is the DG pipe on it. Needed new upper/lower chain rollers and i'm getting some new tires for it. It's fast enough to scare the crap outta me so it should work just fine. Give me some feedback on it as I am learning alot right now!
Welcome aboard Ski. I've read that the full floating rear suspension on the 1982 RM is one of the best designs ever made. Reportedly, Suzuki only changed the design because they were too expensive to produce.
