During the 1970’s, overseas motorcycle manufacturers flooded the US motorcycle market with machines sold below market value, decreasing Harley-Davidson's share of the motorcycle market. In 1982, Harley-Davidson sought protection from the International Trade Commission and requested a tariff on all overseas heavyweight motorcycles. A tariff would allow Harley-Davidson to improve their quality and become a thriving business once again. President Reagan signed the tariff into effect on April 1, 1983. While the act was supposed to last for five years, then CEO Vaughn Beals asked that it be lifted a year early in 1987. Harley-Davidson had grown strong enough to deal with overseas completion without the aid of a tariff. This was the first and only time such a request was made to the ITC and it impressed the US government so much that Ronald Reagan toured the York plant in May of that year.
