Agreed, it looks like a beauty.
The only (hopefully) minor issue that I can see, that it is advertised with 26KW. I guess it was registered this way to meet some regulations of it's time.
I would check with some local bikers if it is possible to register this bike with full power and most importantly via what method is this bike's power reduced. Is this done via an (easy to be removed) carb mod or a different camshaft (would not be that great).
