The Puch 250 SGS (Schwing-Gabel-Sport) was a motorcycle manufactured by the Austrian Steyr Daimler Puch AG in Thondorf near Graz. The motorcycle was powered by a split-single two-stroke engine (two pistons sharing a single combustion chamber). It was marketed in the United States by Sears as the "Allstate 250" or "Twingle", and sold primarily via the Sears catalog. It was a common "first motorcycle" for many riders.
A total of 38,584 Puch 250 SGS motorcycles were produced between its launch on October 1, 1953 and the ending of manufacture in 1970.
