1950s World Champeen NSU Rennmax twin racer is most definitely a twin - a highly developed twin at that - twin bevel drives to cams and all. More hp out of a 250 than most race 350s.

Mixing and matching our NSUs in these posts...

Hi Steve

The first machine pictured was definitely the twin Renmax as pictured in the post immediatly prior to this one.

The production bike based Sportmax did win the 250 World Champs the year after the factory withdrew from official racing but would not have been competitive against the Renmax twin.

This is the Sportmax single. As I mentioned I have a mate who is nuts about these bikes.

Having not seen the pictures I was speculating that it was a SportMax, the RennMax being very rare. If it was indeed a RennMax did it sell?

Sorry about that Rohan. I'll endeavor to not to not expand my comments beyond the immediate subject at hand.

Not a problem Steve, I was just commenting that we had already ranged across quite a wide range of NSU models - the Max being the usual one that folks have met, and technically quite interesting in its own right.
The original pics too were something that hobot found pics of somewhere, and were more for our e-du-cation than anything. A genuine racer Rennmax twin for sale would be worth a fortune, wouldn't be many of them ?
Cheers.
