Some tech details: This bike probably had the
first telescopic forks used on a motorcycle, cylinder heads and
cylinders were one piece, eliminating the need for head gaskets.
The frame was stamped steel plate, there are no frame tubes like
in more modern frames. The engine had a one-piece forged crankshaft
and had carbs with accelerator pumps. Allthough the bike had "only"
35 horsepower, it weighed only approx. 170 kilograms and was able
to do 90 mph, which made it a real superbike in 1934!
