Motorcycle Jawa 350
The Jawa 350 motorcycle, type 634-5-16 is a single-track motor vehicle. It is structurally based on the Jawa 350 touring motorcycle, type 634-8-00. Production of the civilian type 634 began in 1973. In the same year, this motorcycle won one of the toughest motorcycle races in the world, the legendary "Six Day" held that year in the United States. The military type differs from the civilian type mainly in the way of engine lubrication (military type 634-5-16 does not have lubrication with an oil pump), lighting, surface treatment of individual parts and mounting of the carrier. Other interventions in the structure were only small, their goal was to increase reliability (better anti-corrosion treatment, insulation, ...) during demanding operation.
The motorcycle was used to transport people, their personal equipment and armament, as well as luggage and cargo up to a total weight of 180 kg. It was designed for operation on roads - roads, field and forest roads, off-road driving and wading.
