Introduced in production in 1948 was also the first series of three-fifties in the same frame as the JAWA 250 Springer. Initially the machines were marketed under the JAWA - Ogar marque, being For many well-known makes the JAWA of that time has been an inspiration if not a model to be manufactured at "Ogars" the third largest motor cycle manufacturer in pre-war Czechoslovakia. Moreover the factory in Prague Strašnice had in 1948 been incorporated in the JAWA firm. JAWA had also Ogar registered as its trademark.

The JAWA-Ogar three-fifties, later simply JAWA, were two stroke twin cylinders, designed along the same lines as the two-fifties with flat top pistons and inverted scavenging. Their displacement was 344cc (58x65),power output 8.8 KW (12HP), maximum speed 110 km/hour, average consumption 3.5 liters per 100 km. The wheels were shod with 3.00 - 19 size tyres. Until 1950 in production was model 12, parallel with the two-fifty model 10. Following minor modifications models 11 (JAWA 250) and 18 (JAWA 350) began to be manufactured since 1950. Apparent at first sight was the sparser finning of the cylinders of both engines, but the fins were more sizeable for better cooling. The connecting rods and pistons have been changed, too, and therefore the motor cycles were marketed as a new model.

"The most unusual feature is the automatic clutch. The hand control is needed only to engage low gear. After that, all gears can be shifted by pressing down or up on the foot shifting lever. The rider can use the foot lever as a clutch by moving the lever slowly when engaged in low gear. This feature was found to work perfectly." Officer H. Filker, in an Old American Magazine Article after road testing the JAWA TWIN 350 (Sep 1950)
