BMW r7 is an Art Deco bike that was built by an extraordinary engineer Alfred Boning. the bike is absolutely stunning but unfortunately couldn't go into mass production due to high costs for those times.... so it was put to storage until it was found by accident 70 years later. they restored the prototype but it still never went into production. I am a huge fan of BMW in general and do a lot of research...recently I found this sketch of nmoto design ....maybe they will bring it back to life...I can't figure out how to actually add a picture...my comp is acting up so google it guys if you are curious: nmoto.com isnt it beautiful? I would definitely buy
Found it on another site of vintage German motorcycles. I saw one in the BMW museum in Munich a few years ago a must see if you find yourself in that part of the world.
