Matt Drudge just linked a New York Times article from 1983 which proves this.
From the New York Times:
In an unusually strong protectionist action, President Reagan today ordered a tenfold increase in tariffs for imported heavyweight motorcycles.
The impact of Mr. Reagan's action, which followed the unanimous recommendation of his trade advisers, is effectively limited to Japanese manufacturers, which dominate every sector of the American motorcycle market.
The action was exceptional for protecting a single American company, the Harley-Davidson Motor Company of Milwaukee, the sole surviving American maker of motorcycles.
The only comparable trade action by this Administration, the President's decision last May to impose quotas on sugar imports for the first time since 1974, was aimed at an entire industry.
''We're delighted,'' said Vaughn L. Beals, Harley-Davidson's chairman. ''It will give us time that we might otherwise not have had to make manufacturing improvements and bring out new products.''
But it brought angry reaction today from Japanese officials and a threat to file unfair-trade charges against the United States in Geneva.
''We consider it unfortunate that the American side decided to take this kind of drastic measure,'' said Hiroshi Ota, counselor for public affairs at the Japanese Embassy here. He added that Japan was considering taking a formal protest of the action to the General Agreement on Tariffs and Trade.Trump has called for similar action.
