The Austrian Puch factorys engineer Albin Sterbenz converted a few of
the ISDT Gelände-Sport machines for roadracing and participated in
selected races during 1966- 67. Austrian 50cc championship 1969
were won by Adolph Zötch on a works- Puch.
Another fast Dane were succesful on the factory- supported Puch.
Under supervision of service- manager Heinz Schösser, Dan Jeppesen of Copenhagen, raced the
Puch to several victories. Much faster than everybody else, and at a Knutstorp race, suspicions of
an engine capacity of more than 50cc rose! Engineer Sven Håkonsson put an end to the protest,
by verifying the measurements!
Would you believe that the engine were checked again in a race in Austria! A well- prepared bike
and sheer driving talent, put all rumours to shame! At the 1970 RingKnutstorp race, Dan Jeppesen
took second place only beaten by Leif Rosell driving a Jamathi.
