On Monday Reuters reported that Harley-Davidson is launching lightweight motorcycles in Asia and electric bikes globally, in the hope of reviving demand. It comes at a time as the company faces falling sales in the United States and the threat of trade tariffs adding to its costs. Harley-Davidson is trying to boost overseas sales and scrambling to revamp operations as its mainstay customer base ages. Harley wants to woo younger buyers, particularly in Asian markets, with nimbler motorcycles that have smaller engines.
