The advantage two-strokes had over four-strokes was that they completed their power cycle in half the time of a four stroke engine. This meant they could rev very fast, so ‘Das Kleine Wunder’ (the little marvel) was the perfect engine for DKW’s new range of motorcycles. 1928 was a bumper year for DKW. Thousands of motorcycles, all powered by their new engine, practically raced off their production line and year on year sales just keep increasing.
Motorcycle production peaked at 55,000 in 1937 making DKW the largest and most successful motorcycle company in the world.
