1950 Manet Motorcycle

Manet was established in Czechoslovakia to manufacture lightweight motorcycles of 90cc capacity. These were very similar in design to the prewar DKW RT100 (which wasn't actually 100cc as its name suggests). Manet ceased motorcycle production in 1951 and began manufacturing scooters. The most famous vehicle was the Manet Tatran, powered by a 125cc motor. They also built a 50cc scooter, the Pioner which was sold under the Jawa brand-name.

1950 CZ Motorcycle

CZ and Jawa were Czechoslovakia's principle motorcycle manufacturers. Initially they both built very similar two-stroke motorcycles, but by the mid 1950s had differentiated into two separate markets. Jawa built larger capacity civil motorcycles while CZ specialized in lightweights and moto-cross. Both brands enjoyed export success.
