Sometimes Kettenkrad owners ask me, where to buy reproduction sheet metal components for the restoration of a Kettenkrad.
Now we have a producer here in Germany, who makes excellent sheet metal parts.
The SKFK GmbH from Grumbach, near Dresden.

Here is a small excerpt from the catalogue of reproduction parts for the Kettenkrad:

Franz Käppler builds most of the parts himself and to the best of my knowledge, the quality is excellent.
He is eager to help, if special customisation of the parts is required.
