U.S. President Donald Trump on Monday slammed Harley-Davidson Inc. after the motorcycle maker said it would move production for European customers overseas to avoid retaliatory tariffs that could cost it up to $100 million per year.

Trump said he has fought hard for the company and was surprised by its plans, which he described as waving the "White Flag."

Harley-Davidson, the dominant player in the heavyweight U.S. motorcycle market said earlier on Monday it would not pass on any retail or wholesale price increases in the EU and instead focus on shifting some U.S. production.
