Brilliant! any links?

This looks like the sort of person who would have no trouble popping out a 120ยบ V twin BMW motor... :)

Fallert made a bevel drive "V twin" BMW that was something like a 176* or 178* "V"...it looked like a flat twin, but technically was a (very)wide V.

edit...I was wrong...here's the story from "BMW Racing Motorcycles the Mastery of Speed" by Laurel C.Allen and Mark Gardiner...

"...handful of machines built by Werner Fallert. Fallert's frame was a more conventional-looking unit, but his motors eschewed almost all factory components. Taking little more than inspiration from an R100RS motor, Fallert converted it from a two-valve-per-cylinder OHV design to a four-valve overhead cam unit. Like the old works racers, his cams were bevel-driven. Where Krauser and many others had improved ground clearance by raising the motor, shortening the cylinders, and chamfering the valve covers, Fallert actually changed the cylinder axes, turning the motor into a 170-degree shallow vee..."

A long time ago I read an article in The Classic Motorcycle about a guy who converted a flat twin into a V twin, but I thought he started with a Douglas. I didn't see the point but was impressed with his fabrication skills. With all of the work involved I don't understand why he didn't just make a motor from scratch, if that's what he wanted.

Someone made a Douglas flat 4 with the cylinders stacked. Only 2 carbs with very convoluted carb plumbing, I'll dig out some pics, looked very well made, but have not heard it running

Didn't Brough build some thing like that once?

I have a feeling that brough made something using a car engine?


Here is the homemade Douglas. I love the way that this insane bike really looks like a real Douglas.
