Here’s a rough youtube video that has some clips of the big NSU bison 2000 sidecars in action. They sound like cannons!
Ben sends in a link to his excellent Photo Album from his weekend travels.

Hi Steve,
my name is Ben, i live in Germany (near Stuttgart in Swabia) and I did a little trip yesterday to the Technikmuseum Sinsheim. This is a museum full of cars, planes, bikes, tanks and so on. Additionally, this weekend was a bike meeting, too. Just about 1000 bikes, which distracted me from taking pictures. But I got some nice pics of the bikes from the museum, including the 1000 and 2000 ccm NSU Bisons (single cylinder!).
here is the link, feel free to use the pics, so I can donate something to your website (which i like very much)!

Wow! I’ve never heard of this bike! I can only imagine the performance characteristics!
Motorcycle Photo Of The Day 
Very nice video! I was too lazy for searching one.
But the owner seems to be a pretty cool guy. At the beginning he was asked: “And what if you die today, after starting the bike?”. He answers: “Better today, the sun is shining “. This says everything 🙂
