Puch built innovative 2-stroke machines that featured two pistons on a single connecting rod. This unusual arrangement allowed them to use unsymmetrical port timing, which improved the power output. Puch motorcycles were marketed in the U.S. by Sears, Roebuck & Co. from 1950 to 1979 under the Allstate label.
