If I won the lottery and had the dosh the first bike id buy is an original (or close to) Wermacht issue Zundapp KS750 hack. Way over engineered for a bike of the era but sweet. Tank enveloped by huge frame, 2wd, 4 spd road gearbox and low 4 spd "gelande" gear box..
It's engine is a slight Vee (not flat). Lots of $$ for a good example.
I believe the KS 601 was the go to bike for early Elefantreffen runs. GO FOR IT!
Hmmm, post 1000
