Shipments grew 6 percent to 92,848 units. Domestic sales gained only 0.3 percent, but Harley estimated the overall heavyweight motorcycle market was down 1.7 percent for the quarter. Overseas, sales of the bikes rose 29.4 percent, with Canada seeing an increase of 37.4 percent and Europe an increase of 31.2 percent for the quarter. Dealers will hold more rallies and safety programs in the U.S. this year to bring in new riders, young, minorities and women. Fifteen years ago, 2 percent of Harley buyers were women.
