Harley-Davidson is planning to add smaller, more versatile motorcycles to its lineup to attract younger riders, writes Bob Tita for The Wall Street Journal.

Sales of motorcycles in the U.S. have been dropping for three years, as Harley’s retail sales across the country fell 6.4 percent in the second quarter, compared to the same period last year.

In response, the company will introduce a new model of adventure bike and several new middleweight street bikes. The company aims to add up to 100 new and updated models to help attract two million riders here over the next decade.

“We’ve got lots of enthusiasm from people to bring these products to the industry,” said Chief Executive Matt Levatich.

Harley-Davidson is looking to redouble its efforts to sustain its bigger motorcycles sales. Its domestic share for this category slipped in the second quarter, down from 50.4 in the previous quarter.
