Manufacturer: Zbrojovka Ing. F. Janećek, Prague-Nusle II, Czechoslovakia
As the economic situation improved in the second half of the 1930s, the production program of motorcycle factories also increased. Javanese fabryka, which in 1937 year, she has already employed over 2200 employees, striving to construct a means of transport intended for the so-called. mass motorization, began to produce popular cars and motorcycles called Jawa Robot.
Two years of intensive testing had preceded the serial production of the new model. Its design assumptions resulted from the then regulations, favoring light vehicles (bicycles with grippy motors, mopedy, light motorcycles), equipped with power units with a capacity of up to 100 cm3. A two-wheeled vehicle of this category did not have to be insured, was not subject to registration, tax was not paid for it, drivers could ride it - after the age of fourteen - because driving this vehicle did not require a driving license.
Java 98 The robot had a two-stroke single-cylinder power unit with a capacity in a double-pressed frame 98,8 cm3 (with reverse flushing of the Schnurle system) and power 2 kW (3,7 KM) at 3700 rpm. This engine was wet equipped, multi-plate clutch and locked to a three-speed gearbox, manually controlled. The patent-protected design made it possible to transfer the driving force to the rear wheel by means of a chain transmission in two ways: from the engine or with the pedals, according to Czechoslovak regulations, vehicles of this class had to be equipped. Jawa Robot had a front suspension with a trapezoidal fork, adjustable saddle and handlebars. Thanks to its low weight - only 49 kg - it was a steerable vehicle and kept the road well. The maximum speed of this vehicle was 65 km / h and fuel consumption 1.2-2 liters / 100 km. This vehicle quickly became a very popular means of transport. After the Second World War, it was produced with minor improvements to 1947 year.
