I was born and lived in Europe and I never heard of it . We used to drool over Munch Mammut which was powered by car engine (NSU), that was super bike for its era.
I would happily ride one of those behemoths. They were steampunk before steampunk existed. If anyone has one out in the barn, I'm your huckleberry.

Here's an interesting fact about the Brough Superior. The manufacturer's father owned a successful motorcycle company eponymously named Brough. He was rather put out when his son launched the Superior marque, as it indicated his own product was inferior.
Me too. I would not mind owning some of my old ones now. For you know it all what bike is the top picture?
I owned a Brougham once. A 1980 Cadillac Fleetwood Brougham. My daughters hated us taking them to school in it.
Meh. IMO the engine should be the star of the show and it's not. Looks like a warmed-over TL1000 engine.
