I found a note that Gunther Vogt sent me in 2003. It has the 2 mopeds listed that uses the same clutch plates as the Sachs 100,125 and the 175/6
They are Hercules Ultra 80 and RX9 are the models.
The Surflex part # for a 5 disk set is S1147/B
We may be able to get the plates from a Moped dealer here in the states with those #'s
