Simson GS50

from Wikipedia, the free encyclopedia

The Simson GS50 was an off-road motorcycle with 50 cm³ displacement and street legal (KTA type certificates 593 and 877)

The light motorcycle, which was built in several small series and in various designs by the sports department of VEB Fahrzeug- und Jagdwaffenwerk Simson (company) in the GDR was intended for off-road sport (six-day drive, etc.) and therefore had to be approved for public road traffic. Since it did not meet all road traffic regulations, various exemptions were granted. In the GDR it was only sold to motorcycle sports clubs of the ADMV or the Society for Sport and Technology and was the rarest light motorcycle from the Simson factories. Therefore it is hardly available today. Some vehicles were also exported. It was presented in 1962, at that time still with 3 gears and 4.8 HP engine power. The 1963 version also had 3 gears, but 5.5 hp at 8000 rpm. A small series of 25 vehicles was built in 1963, and twice that number was estimated for 1964.

The 1963/64 version had a full swing chassis with hydraulically damped spring struts and 19 "running wheels. The full hub brakes corresponded to the series version on the Vogel models . The engine was structurally similar to the conventional series model of the engines built by Simson Gears were available.

There was also the GS 75 and GS 75-1 with 75 cm³ as sister models
