The Jawa 350 Type 354 , also known as kývačka , was a motorcycle with a two-stroke two - cylinder engine manufactured by Jawa in Czechoslovakia and manufactured from 1954 to 1964.
history
The Jawa 350 "Pérák", which was modern for the time, appeared as early as the late 1940s, but still with straight-line suspension . This model was replaced in 1954 by the type 354 "Kývačka" (pronounced kiewatschka ), which had a new chassis with a modern two-arm rear swing arm with struts . A distinctive shape and red paintwork with chrome-plated panels on the tank were distinguishing features. The vehicles were exported many times, including to the GDR . With the concept, which was less focused on functionality and more on design, the motorcycles formed a contrast to the MZ machines. In 1962 the 250 and 350 types (internally now 559/02 and 354/06) were slightly changed. This mainly affected the handlebar section with handlebar trim and handlebar ends pointing more towards the rear, as well as a modified seat and a new rear light. In addition, an increase in engine power to 18 hp was announced, but this did not go into series production. For export markets there was a version called Supersport with a single-cylinder engine and an engine output increased to 20 hp.
The Type 354 was known for its shapely exterior with compromises in functionality. The relatively narrow bench seat was arranged quite low, so that fatigue quickly arose on longer journeys. A bigger problem was the engine that was not fully throttle-proof, piston jams were not uncommon under high loads and summer temperatures, but rather the rule. The problem was not solved until 1963, among other things by using a different light metal alloy for the pistons. The now full-throttle-proof machines, however, had a significantly higher fuel consumption, which could amount to an average of 7.0 l / 100 km with brisk driving style. Another weakness of the Type 354 was that the rear wheel tended to break away, especially on wet roads.
