IZH-49
The IZH-49 ( Russian ИЖ-49 , also ISH-49 or ISCH-49 ) is a Soviet motorcycle . Contrary to what is often assumed, it is not a copy or a replica of the German DKW NZ 350 , but a modified extension on the original DKW production machines.
As early as 1930, the centrally controlled motorcycle construction department in the Soviet Union decided to produce a copy of the German DKW Luxus 300 . The type L300 was manufactured in the Promet works in Leningrad as a DKW license.
The early interest in the reliability of the DKW two-stroke engines led to the fact that after the end of the Second World War the Soviets seized the opportunity and dismantled the production facilities of the DKW works in Zschopau at the beginning of July 1945 and in Izhevsk on the Urals, where the Izhevskians were already doing reparations Motor factory (Ischmasch) existed, rebuilt. DKW chief designer Hermann Weber , the engineers Heydenreich, Schmidt and Ernst Volkmar also went to the Urals to rebuild the production facilities there, albeit involuntarily. Hermann Weber died in Ischewsk, the others returned in 1948/1949/1951. At the same time, other employees of the former DKW staff were working in the Russian planning office in Chemnitz on the further development of the NZ 350/1, which would later become the Izh-49.
Initially, the IZH-350 was built identically to the NZ 350, and the first 83 motorcycles are said to have been made from original DKW parts. 126,297 pieces of the IZH-350 were built up to 1951.
In 1948 the IZH-350 C was built in Izhevsk with a telescopic spring fork and now 14 HP.
From 1951, the modified IZH-49 was built. The main changes were the use of a telescopic fork on the front wheel, as well as a rear swing arm, the spring-damper elements of which were modeled on a telescopic straight path suspension (the sliding blocks that linked the swing arm to the straight path spring struts were highly stressed wear parts). The tried-and-tested central tubular frame of the DKW NZ 350 was retained, but extended to the rear by welding, thus making the wheelbase 1.5 centimeters longer. The two-stroke fuel was then poured directly into a single-chamber tank.
The IZH-49 was also the first motorcycle from the Izhevsk Motor Factory to have a model with a sidecar. It was built in 507,603 pieces from 1951 to 1958 and was one of the most built motorcycles in Russia at the time.
Through improvements with the IZH-54 and IZH-55, it was then replaced in 1956 by the IZH-56 , which got a completely new chassis (tubular frame with double girders and strut swing arm).
engine
The IZH-49 is powered by a single-cylinder two-stroke engine with a capacity of 346 cm³ and an output of 10.5 to 11.5 hp at 3,200 rpm. The top speed is 110 km / h, the consumption is around 4.5 l per 100 km.
