Document 6: Harley-Davidson: In 1981, AMF sold the company to a group of 13 investors led by Vaughn Beals and Willie G. Davidson for $80 million.  Inventory was strictly controlled using the just-in-time system.In the early eighties, Harley-Davidson claimed that Japanese manufacturers were importing motorcycles into the US in such volume as to harm or threaten to harm domestic producers. After an investigation by the U.S. International Trade Commission, President Reagan in 1983 imposed a 45 percent tariff on imported bikes with engine capacities greater than 700 cc. Harley-Davidson subsequently rejected offers of assistance from Japanese motorcycle makers. However, the company did offer to drop the request for the tariff in exchange for loan guarantees from the Japanese.Rather than trying to match the Japanese, the new management deliberately exploited the "retro" appeal of the machines, building motorcycles that deliberately adopted the look and feel of their earlier machines and the subsequent customizations of owners of that era. Many components such as brakes, forks, shocks, carburetors, electrics and wheels were outsourced from foreign manufacturers and quality increased, technical improvements were made, and buyers slowly returned.
