SFM Junak

Junak is a brand of Polish motorcycles, the only four-stroke models produced in Poland between World War II and the Revolutions of 1989.

The Junak frame was produced by SFM in Szczecin while the engines were made by ZSM in Łódź.

The governing system and inconvenient localization of the production line led to difficulties in ensuring quality.

Its characteristic exhaust and loud valve train are easily recognized, which is another similarity with the Sokół and the only with the Harley.

Half a century later the Junak is still the most advanced Polish motorcycle in the heavy category as no other models were produced.
