While not for sale, starting today, select consumers across the United States will be able to ride and provide feedback on the new motorcycle during a series of events scheduled through the remainder of the year. Harley said it will likely be several years before its LiveWire goes on sale. (AP Photo/Harley-Davidson, Ray Stubblebine) ( Electric Motorcycles )
