Title: NGC - Zundapp K7800 - 4 cyl Boxer?
Post by: canuck750 on October 25, 2015, 06:59:47 PM

Spotted this on German Ebay, 1938 Zundap, never seen one before, looks to be a 4 cylinder boxer??

Very cool, it would make a fantastic project and I think it would be one of a kind!

Tell you what Jim, you buy it, import it and get it road legal (no need for any cosmetics)  :drool:  and I'll ride my 750S out to Edmonton for you to play  :laugh: with while I ride the Zundapp up to Inuvik. Deal? :thumb:

Beautiful motorcycles.  Always liked the appearance of the stamped steel frames BMW and Zundapp used in the 1930s.  I'm having a mental block at the moment .... but was it Zundapp or DKW that used the chain and sprocket transmission vs having gears that meshed?  From a cost standpoint, it makes sense. Instead of precision gears meshing, the tranny had chains and sprockets with different ratios inside the box.  Just can't remember if it was Zundapp or DKW.  I know it wasn't BMW.

Thanks for the answer!  I knew it was one or the other ..... just couldn't quite remember which.

Perhaps it is a twin with twin spark and an oval piston? :wink:

Beautiful bike!

A quick google showed that it is a four cylinder four stroke side valve engine. The induction must run from inside the case in some way.

The lines of the bike is also pretty similar to the Danish build Nimbus motorcycle from 1934.
