Harley developed the “45” in 1929, named for the engine’s capacity in cubic inches, as a competitor to Indian’s flathead 750, but with limited success until the U.S. entry into the World War II hostilities, when demand for the reliable model really took off. Known as The Liberator, 90,000 bikes rolled off the production line until 1945, heading for Britain, mainland Europe, Africa, etc. These military Harleys benefited from the new aluminum cylinder heads fitted to the civilian version from 1939 and came with a full complement of equipment including D-shaped footboards, crash bars, skid plates, cargo racks and panniers. Designated WLA (Army) or WLC for the Commonwealth (UK and Canada), the Harley 45 saw action in just about every theater of war. “De-mobbed” Harleys helped meet the upsurge in demand for motorcycles in the immediate post-war years, doing much to establish the marque’s reputation worldwide. However, WLA production started again in 1950 for Korean War active service and finished in 1952.
The WLA’s motor was a 45ci or 739cc, 45-degree flathead or side-valve v-twin which built itself a massive reputation for ease-of-use, both riding and maintenance, and longevity, and thus was perfect for winning wars. However, it also proved itself in racing, as the four-camshaft motor was easily tuned, and it formed the basis for Harley-Davidson’s entry into Class C racing.
The de-mobbed example on offer here, has been part of a discerning collection of motorcycles for several years. Purchased as a partial build when the owner passed away, the bike was complete but for a handful of nuts and bolts, and just in need of completion. The engine enjoys a fresh top end, rebuilt by engine guru, Dean Collinson, including new cylinders, pistons, rings, valves, guides and springs, at standard bore. The bottom end was inspected and appeared to be in good condition. A new auto-advance distributor was installed for easy starting, along with a new wiring loom, and original 6V lighting. The bike’s system charges and works well. A new Mikuni carb supplied by 45 Restoration was also installed, aiming for easy starting. A new standard throttle assembly for easy operation was installed with a new eproduction speedometer. Original parts are available should the new owner want to return the bike to stock.
The bike starts easily and the engine sounds really taut. It shifts well and is a blast to ride!
