Ain't a Paris Dakar, not got the right bits and they were not released until 1984, its not even a GS as listed it's a g/s as Essjay has said, but you'd have to smell of wee to understand the difference.
Herr Wurm brought one of these back from the fatherland recently. A few modifications and newly rebuilt gearbox ( done by the premier g/box guy over there ). Nice bike. Reinhold's that is, not that one.
