1912 saw some serious growth for Harley-Davidson, with the construction of a new five-story building that will eventually become the Motor Company's headquarters. Within 10 years, H-D had expanded its dealership network to over 200 Dealers nationwide. H-D also started exporting motorcycles to Japan, specifically for the Japanese Army. The X-8-E shown here had a 61ci V-Twin that now came standard with the Bosch magneto, and twist-grip compression release. This was also the only year the engine had iron pistons, as opposed to the iron-alloy pistons that would follow.
