Brown Derny Type Tandem Grand Tourisme from 1952 with one cylinder, 100 cc. Max. speed: 60 km/h
Derny is the brand name of a former French light motorcycle manufacturer called Roger Derny. The Roger Derny et Fils company was created in Vichy in 1930 and closed in 1958.
At that time, the company had tried to relaunch itself, by presenting itself in other markets than its main niche of cycle trainer motorcycles by producing an elegant semi-streamlined light motorcycle called “the Horsefly” (a nod to the Italian Vespa which means “wasp” in French) whose surprisingly modern design was due to the designer Roger Tallon.
