Harley-Davidson's first flathead V-twin appeared in 1929 as the Model D. Its 45-cubic-inch engine was smaller than the company's existing 61- and 74-cubic-inch F-head V-twins, which then became known as "Big Twins."

The latter switched to a flathead design the following year, but those larger engines were neither as reliable nor as long-lived as the understressed "Forty-five."

Though the Forty-five was no powerhouse, it proved to be a versatile engine that remained in production for more than four decades.

During that time it served duty not only in street motorcycles, but also in three-wheeled Servi-Cars (1933-1973), military WLAs of the 1940s, and WR racing bikes of the 1940s and 1950s.

By 1948, the Forty-five was powering a street model called the WL. It looked very similar to Harley's Big Twin flatheads of the era, the most noticeable visual difference being that WLs had their drive chains on the right side of the bike, while Big Twins had them on the left.

Though 1948 would prove to be the final year for Big Twin flatheads, the WL lasted through 1951, after which it was replaced by the K-series carrying a redesigned 45-cubic-inch flathead V-twin with unit construction (motor and transmission in one case).
