V twin BMW

About 40 years ago, I'm sure I heard about someone converting a BMW flat twin into a V-twin. (New crankcases etc) It may well have been the earlier R60, which would be more obvious because of the pushrods.

Is this a figment of my imagination, or did it actually happen..? :?

And no, I'm not planning it. :)

(This bumped back into memory while I was reading about the RE Musket.)

Edit: btw this was when I lived in Australia, so it probably was an Australian project.

Amol Precision canted the cylinders up just a bit for ground clearance, but that is all I know/remember of any V.

"This bike #95 is owned by Amol Precision Corp. of Dumont , New Jersey - it is a Honda CB750 4 cylinder with factory race kit - the rider who is working on it is Kurt Liebmann - his family owns Amol Precision Corp. The second bike behind is the Amol Precision's ( OL Special) - it is a BMW Rennsport produced by Kurt's father Oscar Liebmann, who was a master machinist. The 500cc engine is much modified - Oscar Liebmann Special - and has a slight incline to the cylinders to improve corner clearance- the internal improvements were both in design and material. I worked for and raced bikes for Amol during this period. This was one fine handling machine."

That has got to be a $hit load of work on an RS54. :shock:

What I remember may have been a 120ยบ V and I'm pretty sure it was pushrod.

That Oscar Liebmann Special is beautiful.
