FIS Poland

Originated by two Polish motor mechanics with an interest in speedway, they were Tadeusz Fedki, Romould Izewiski and their favoured speedway track, Stalwocy: FIS  - deciding to build an engine followed a humiliating defeat of their Stalwocy team in 1952. Aircraft manufactures PLZ agreed to help the pair and the engine was dually built, and at its first outing it broke the track record: now for a frame to complement.

The frame was made, it was of a fairly conventional design made noticeable by being copper plated, it did also have a larger than normal fuel tank and smaller than usual bracing for the forks.
