Contents • • • • • • • • • Model designation [ ] The model number breaks down as follows: • W: the W family of motorcycles. Harley-Davidson (except in very early models) gives a letter designation for each model family. The W series at the time was the newest incarnation of the 45-cubic-inch (740 cm 3) motor, and was developed from the earlier R family 1932–1936. • L: 'high compression', in the usual HD scheme.

History [ ] Harley-Davidson began producing the WLA in small numbers in 1940, as part of a general military expansion. The later entry of the United States into World War II saw significantly increased production, with over 90,000 being produced during the war (along with spare parts the equivalent of many more).

Harley-Davidson would also produce a close WLA variant for the Canadian Army called the WLC and would also supply smaller numbers to the UK, South Africa, and other allies, as well as filling orders for different models from the Navy and Marine Corps. Unusually, all the WLAs produced after, regardless of the actual year, would be given serial numbers indicating 1942 production. Thus, war-time machines would come to be known as 42WLAs.

This may have been in recognition of the use of the continued use of the same specification. Most WLCs were produced in 1943, and are marked 43WLC.
