Sprocket rear, Zundapp KS50 Esjot 38T 415

Esjot drives are made in Germany. Exact dimensional tolerance and they last at least twice as long as Asian-made drives. Buy an Esjot chain and you will get the best possible transmission. This drive should have a 415 H chain. Esjot manufactured drives for Zündapp, Kreidler, Sachs and a number of other mopeds already in the 60s and 70s.
