Unfortuntely the sound on Youtube is not so good like in original. Once, on a NSU-meeting I slept in my K 70 besides on of these little hammers. Early in the morning its 1300 ccm-engine in racing-trim woke me up. Sure, there are some more great chances to be woken up in hte morning, but this wasn 't really bad.


Yes, Youtube destroys the original sound totally...

No sound in this video for Max -not far away from your home? - I cannot recognize the model, but it's surely not there since 60 years. It looks like early 60ies.
