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. -

Engine and trans of Oscar Liebmann Special BMW Rennsport 500cc.
The engine has SOHC and drive tower is visible in photo on top of
cylinder. There are two spark plugs per cylinder. The gearbox is
five speed. I had this engine to 10,000 rpm and others have had it
higher with no mishaps. The engine produces a unique noise of
mechanical precision.- info from Chuck Dearborn
