NSU (Audi) with R080, ...... was produced also with rotary motors. A revolution of vehicle technicals at this time.
I sure remember the RO80
...unreliable, thirsty-as-all Rotaries, crap engines and a fierce reputation as a local planter-box.
That piece of junk cost NSU its neck, driving it into the arms of Audi/VW.
They should've stuck with the little Prinz!
What a hot, little jigger at the time, the 1200TTS was one monster of a pocket-rocket...King of the hillclimbs and dozens of national titles.
That engine was later fuel injected (mechanically) for the 100hp TTS-E
Muench Mammut (Mammoth)....300kg of bike -madness.
Them were the times...
