A close up view of the engine. The similarities with BMW's boxers are hard to deny, but
the Zundapp KS601 engine was developed entirely by Zündapp-Werke.
The chrome cover on the front houses both the ignition points and the generator's brushes
and commutator. The Cylinder above is the voltage regulator. Beneath the engine top cover
is the ignition coil.
The Zundapp KS601 crankshaft is a one piece unit, unlike the BMWs of that era which had
pressed crankshafts. The Zundapp connecting rod incorporates a removable end cap which
houses needle bearings running in split needle cages. A unique arrangement that looks a
little iffy but seems to hold up well. The wrist pin end of the con rod has a pressed
bushing. Forced oil lubrication is used throughout the engine.

The 597cc Zundapp KS601 engine. Basically the KS600 Engine with some
technical improvements, so they called it the 601 to distinguish the two.
