Guide To Bike Tune Up

By Etta Bowen


During World War II the motorcycle was used on a large scale. All warring nations presented their production to military Motorcycles. The American motorcycle industry, represented by Harley-Davidson and Indian, produced over 300,000 motorcycles, the British industry 425,000 motorcycles for the Allies. The most copied motorcycle in world: a DKW RT 125, 1939-1965 (bike tune up). The motorcycle was used in post-war period as a "cheaper car replacement". The motorcycles should be robust, reliable and simple in construction. The journalist Ernst Leverkus called corresponding models "Westerwald motorcycles" and led as examples of Ardi B 250, BMW R 24, NSU 251 OSL, Triumph BDG, Victoria KR.

In same year the brothers Werner in France developed a motorcycle with front wheel drive. With the technical innovation of spray nozzle carburetor, patented by Wilhelm Maybach in 1893, and the magneto ignition, a patent by Robert Bosch in 1901, the motorcycle was much easier to use. The development of motorcycle technology was coined until First World War only by European and American manufacturers in 1902 presented a Griffon Motorcycle with V-engine produces.

These statements allow Americans to attribute authorship of invention of motorcycle. However, unlike the invention of Perreaux, there remains no trace, not even a certificate proving its existence. The invention of Daimler, from 1885, was designed in order to test the powered motor oil. It was equipped with stabilizing side wheels, so four wheels in total. We can, however, argue that Daimler was first motorcycle with an internal combustion engine.

Manufacturing motorcycles has used some technological innovations: In 1887, the French Millet motorcycle manufactures and sells a few copies of a motorcycle with a petrol engine 5-cylinder radial placed in rear wheel. In 1894, Hildebrand & Wolfmuller sells a motorcycle equipped with a horizontal twin-cylinder 1490 cc which has initial real sales network in history.

In 1969, Honda CB 750 Four with a trend-setting motorcycle with a transversely mounted four-cylinder four-stroke engine and hydraulic disc brake in front, followed by the 1972 Kawasaki 900 as first modern supermotorcycle. Van Veen 1976 provided for the OCR 1000, first electronic ignition. 1980 Kawasaki offered at the Z 1000 Fuel Injection first electronic gasoline injection in a series of motorcycle.

1928 DKW - due to changing tax laws and the introduction of reverse circulation in two-stroke engine - the largest motorcycle manufacturer in world. The two-stroke boom ensured that as early as 1932 in Germany more mopeds were registered as motorcycles. Gilera used in 1934 for first time a transversely mounted four-cylinder four-stroke engine in racing machine "Rondine".

1935 BMW introduced the telescopic fork in front, in same year built by the Japanese manufacturer Koto Trading Company, a subsidiary of Sankyo, first Harley-Davidson Flathead licenses after. Koto Trading was first Japanese motorcycle manufacturer. Honda (1948), Suzuki (1952), Yamaha (1954) and Kawasaki (1961) built after the Second World War Motorcycles.

The history of motorcycle is first history of bicycle. After 1817 the "running machine" by Karl Drais represented the beginning, the crank was invented in 1860s. Pierre Michaux developed in 1869 the steam valve, which is considered the forerunner of motorcycle; Steam wheels were made up in 1890s in United States.
