Harley Davidson 1941 WLD Sport Solo

Harley Davidson had originally followed Indian when the latter had produced its first 45 cu. in. side-valve machine in 1927. Initially, the Indian 45s were the most highly regarded, but by the time Harley introduced its W-series in 1937, it was the Milwaukee-built bikes that enjoyed the better specification and reputation. Replacing the R-series—with which they had much in common—the three models in the original lineup were the basic W, this high-compression WLD, and the competition model WLDR. The main difference over the Rs was in the new styling, which mimicked the classy 61 Knucklehead that had been introduced the previous year. By the time this bike was built Harley was offering a range of factory-fitted accessory packages. Extras on this WLD include chrome spotlights, chrome trim on the mudguards, and a front fender light..

The 1941 model shown here is rare because by this date most of Harley’s production was devoted to military machines. The 45s were basic, robust machines that made them ideal for converting to military bikes. Just like their big brother, the 45s now had teardrop tanks with an  integrated instrument panel and curved mudguards, creating a quality range that further established Harley as the market leader.

Harley Davidson 1935 RL

When the original D-series Harley 45s were introduced in 1929, they were nicknamed the “three-cylinder Harleys” because their vertically mounted generators resembled an extra cylinder. Harley-Davidson produced these bikes in response to the success of the popular Indian Scout, but the D-series was not considered a success and it was replaced, in 1932, by the R-series. One of the benefits of the V-twin engine design is its narrow width, keeping the weight of the machine close to the center line.

The stand was fitted until Harley-Davidson adopted rear suspension. The critical change was the new frame, which now featured a curved front downtube and allowed the fitting of a conventional horizontal generator in front of the engine. These 45s were available in four versions: the basic R model, the high-compression RL, the RLD, and sidecar RS. This bike, with its diamond graphics and airflow taillight dates from 1935, though the engine number indicates that it is a 1932 motor. This kind of contradictory evidence is not uncommon when dealing with many years of history. When the R-series was introduced in 1932, the D-series 45 unit was totally reworked, with modifications to the flywheels, crankcases, barrels, pistons, conrods, and oil pump. There were only a few minor internal changes to the engine between 1932 and 1935. The Rs were replaced by the W-series in 1936. While the European market considered a 750cc machine to be a big bike, the R-series were the smallest bikes in Harley’s range in the mid-1930s.
