NSU 200 and Other Motorbikes, Palace of Culture and Science, Warsaw, Poland, 2007

The science and technology museum at the Palace of Culture and Science has a substantial motorcycle collection, even if it isn't anywhere close to being the world's largest. One of the displays is this NSU 200, a German make that also produced cars. A fascinating Wiki can be found here:
