Motorcycle After World War II

Motorcycle After World War II, some American veterans found a replacement for the camaraderie, excitement, danger and speed of life at war in motorcycles. Grouped into loosely organized clubs, motorcycle riders in the U.S. created a new social institution—the motorcyclists or "bikers"—which was later skewed by the "outlaw" persona Marlon Brando portrayed in the 1954 film The Wild One.

In Europe, on the other hand, post-war motorcycle producers were more concerned with designing practical, economical transportation than the social aspects, or "biker" image. Italian designer Piaggio introduced the Vespa in 1946, which experienced immediate and widespread popularity. Imports from the UK, Italy and Germany, thus found a niche in U.S. markets that American bikes did not fill.

The BSA Group purchased Triumph Motorcycles in 1951 to become the largest producer of motorcycles in the world claiming "one in four". The German NSU was the largest manufacturer from 1955 until the 1970s when Honda became the largest manufacturer—a title now claimed by Indian bike firm Hero Honda, which specialises in small motorcycles throughout India and similar markets.

 British manufacturers Triumph, BSA, and Norton retained a dominant position in some markets until the rise of the Japanese manufacturers (led by Honda) in the late 1960s and early 1970s. The role of the motorcycle shifted in the 1960s, from the tool of a life to a toy of a lifestyle. It became part of an image, of status, a cultural icon for individualism, a prop in Hollywood B-movies.

The motorcycle also became a recreational machine for sport and leisure, a vehicle for carefree youth, not essential transportation for the mature family man or woman, and the Japanese were able to produce modern designs more quickly, more cheaply, and of better quality than their competitors. Their motorbikes were more stylish and more reliable, so the British manufacturers fell behind as mass-market producers.

The Honda Motor Co., which was officially founded in Japan on September 24, 1948, introduced their SOHC inline 4-cylinder 750 in 1969, which was inexpensive and immediately successful. It was not a high-performance bike, but it established the across-the-frame-4 engine configuration as a design with huge potential for power and performance. Despite being much more complex than any other mass-market motorcycle, it was the most reliable large motorcycle on the road.[citation needed]

Shortly after the introduction of the SOHC, Kawasaki demonstrated the potential of the four-cycle four-cylinder engine with the introduction of the KZ900. The only motorcycle that outperformed the KZ900 was another Kawasaki, the H1, a much smaller and lighter 3-cylinder, two-cycle engine.[citation needed] The H1 was prone to fouling, and was considered dangerous by many riders.[citation needed]

The Suzuki Motor Co., Ltd., Kawasaki Heavy Industries and the Yamaha Motor Corporation each started producing motorcycles in the 1950s. Meanwhile, the sun was setting on British dominion over the big-displacement motorbike market.

Japanese dominance

The excellence of Japanese motorcycles caused similar effects in all "Western" markets: many Italian bike firms either went bust or only just managed to survive. Also as a result, in Germany, BMW's worldwide sales sagged in the 1960s but came back strongly with the introduction of a completely redesigned "slash-5" series for model year 1970.

From the 1960s through the 1990s, small two-stroke motorcycles were popular worldwide, partly as a result of the East German Walter Kaaden's engine work in the 1950s, later acquired by Suzuki via stolen plans supplied by MZ rider Ernst Degner, who defected to the West in 1961 part way through a race at the Nuerburgring.

Harley-Davidson (HD) in the U.S. at the time suffered from the same problems as the European firms, but its unique product range, American tariff laws and nationalism-driven customer loyalty allowed it to survive. One alleged flaw, however, was retaining the characteristic HD 45° engine vee-angle, which causes excess vibration as well as the characteristic loping HD sound.

A factory full fairing was introduced by BMW motorcycles in the R100RS of 1977, the first factory fairing produced in quantity. In 1980, BMW stimulated the "adventure touring" category of motorcycling with its R80G/S. Then, in 1981, BMW introduced the first motorcycle with standard anti-lock-brakes (ABS) in its K-series motorcycles. As a result, BMW has seen increased popularity in the motorcycle marketplace.
