Only 1000 841's were made as test, unfortunately it never got further. That would have been a beast.

One of the very few things I still keep
is that I ever sold my 1955 BMW R67/3 with Steip sidecar. The Steip my brother bought and I have it back in heritage, the bike itself I sold in 1980 because I desperately needed $$$ for my study and trip to Canada. Actually, in retrospect, not that desperate, I could have survived easily without.

The BMW has a beautiful wing-ended front fender. Watch the 841: it has a cardan drive, same as the BMW.. The 841 has a Bugatti-like V-engine sticking sideways, the BMW has a boxer-engine. And most of all, I like the sound, as it is described in the Netherlands: every streetlight pole on stroke.
And like Floridianson: double in spades. Time a bike gets the recognition it deserves as MV of the month:
