Harley-Davidson again produced large numbers of motorcycles for the US Army in World War II and resumed civilian production afterwards, producing a range of large V-twin motorcycles that were successful both on racetracks and for private buyers.
Harley-Davidson, on the eve World War II, was already supplying the Army with a military-specific version of its 45" WL line, called the WLA. (The A in this case stood for "Army".) Upon the outbreak of war, the company, along with other manufacturing enterprises, shifted to war work. Over 90,000 military motorcycles, mostly WLAs and WLCs (the Canadian version) would be produced, many to be provided to allies.
Harley produced the WLC for the Canadian military.Shipments to the Soviet Union under the Lend-Lease program numbered at least 30,000. The WLAs produced during all years of war production would, unusually, have 1942 serial numbers. Production of the WLA stopped at the end of the war, though it would resume production from 1949 to 1952 due to the Korean War.
The U.S. Army also asked Harley-Davidson to produce a new motorcycle with many of the features of BMW's side-valve and shaft-driven R71. Harley largely copied the BMW engine and drive train and produced the shaft-driven 750 cc 1942 Harley-Davidson XA. Due to the superior cooling of an opposed twin, Harley's XA cylinder heads ran 100 °F (55 °C) cooler than its V-twins.[22] The XA never entered full production: the motorcycle by that time had been eclipsed by the Jeep as the Army's general purpose vehicle, and the WLA—already in production—was sufficient for its limited police, escort, and courier roles. Only 1,000 were made and the XA never went into full production. It remains the only shaft-driven Harley-Davidson ever made.
