Original 1942…Harley-Davidson WLA Flathead

The Thunderbike exhibition is a bit richer – A 1942 WLA Flathead is now also part of our historical Collection!

As early as 1938, Harley-Davidson had the idea of ​​producing military machines against the political background. So that Harley-Davidson could do the “business”. In 1940, the US Army ordered the first 745 units of a military version of the WL, the WLA, with revised front fork, aluminum cylinder heads, crash bars, saddle and rifle bag.

The performance of the 250 kg heavy machine was 23.5 hp at 4,600 rpm. From this model, about 88,000 copies were produced between 1940 and 1945; making the WLA one of Harley-Davidson’s most popular models. The V-engine, which became known as the Flathead, was a side-mounted variant of the Harley-Davidson in various variations, later produced in large quantities for the military until 1948.
