I'm not to up to date on these but it looks slightly older than a '71 125 I have in my shop. The only difference I can see is the front fender on the one you pictured.
The one that is here has a broken steering tunnel in the chassis. The owner couldn't figure out why it wont drive in a straight line. He rode it here from EastPoint... 15 miles at 55 mph.
I gave him a quote, and made a fair offer for the bike. We'll see what he decides.
