Simson produced more than 300,000 motorcycles of the type AWO 425. There was 2 models: touring and sport. A 1960 sport model that was shaft driven with 250 cc four stroke engine and twin shock rear suspension is the platform for this custom motorcycle. Bikers from East European countries seem to be still very attached to this brand and I guess it’s the reason why Zsolt Muller from Muce Choppers in Hungary spent so much time and money customizing it.
