Berliner DDR Motorrad-Museum
Not exactly a team effort, yet totally worth mentioning!
Visiting Berlin late summer 2015, I spotted this rather small yet very special museum. It shows quite some motorcycles from the time before the take down of 'the wall'.
Brands of 'Motorräder', 'Motorroller' and 'Mopeds' of the manufacturers DKW/ IFA/ MZ, Simson-Suhl, IWL und EMW... very rare indeed!
... and even a 'lost' BMW in the corner.
