I looked at this today, It has 66k on the speedo but I doubt very much it is original.
It generally looks tired, leaking fork seals, oil soaked front brakes.
The thing I have never seen before is the engine number is 5N5 419 but the frame number is
5N5 440 and there is no compliance plate and no rivett holes where it could have been.
He had rego papers and the same numbers were recorded on the papers so reg is ok.
