Earnings were in line with company expectations, the release stated.
Restructuring efforts in Springettsbury Township have followed a high-profile decision in 2009 on whether to leave York County for another state to become more cost effective or stay put.
Harley reported net income for the third quarter of this year of about $134 million, or 59 cents per diluted share, compared with about $183.6 million, or 78 cents per diluted share, in the year-ago period, according to the release.
The company said it believes U.S. dealer sales of new motorcycles were negatively affected for the quarter by the ERP implementation lowering the number of available new motorcycles and by a shift in launching the new model year from late July to late August, the release stated.
Worldwide new motorcycle retail sales in the quarter were down 1.3 percent, including a 5.2 percent decrease in unit sales domestically and a 7.6 percent increase in international markets, according to the release.
Shares of Harley are traded on the New York Stock Exchange under the ticker symbol HOG.
