Kettenkraftrad
A german WW2 army vehicle that is a cross between a tank and a motorcycle(!),
powered by a NSU engine, imagine riding this to your local bar.........

Andreas from Germany actually owns one of these beasts
and has a Kettenkrad-homepage with lots of pictures of it!
He tells me it was powered by an Opel Olympia engine,
and not a NSU as I thought...

Did you know, that the Moto Guzzi V-twin engine
was originally used for this Ammo-carrier instead
of for a motorcycle?
