In the late summer of 1929, Harley-Davidson introduced its 45 cubic inches (738 cc) flathead V-Twin sv (Side Valve) to compete with the Indian 101 Scout and the Excelsior Super X. This was the “D” model, produced from 1929 to 1931. The 2.745 in (69.7 mm) bore and 3.8125 in (96.8 mm) stroke would continue in most versions of the 750 engine; exceptions include the XA and the XR750. The Solo and Sport Solo lineup were unveiled in 1934, which included the WL WLDR W WLD G GE lines.

On the eve of World War II, Harley-Davidson was already supplying the Army with a military-specific version of its 45 cubic inches (738 cc) WL line, called the WLA. (The A in this case stood for “Army”.) Upon the outbreak of war, the company, along with most 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-Davidson received two Army-Navy E Awards, one in 1943 and the other in 1945, which were awarded for Excellence in Production.
