During the Second World War motorcycles played an important role in military transportation and communication. Among the most famous military motorcycles were those produced by Harley-Davidson for the Allied forces.
Harley-Davidson motorcycles were used for reconnaissance, courier duties, escort services, and military police operations. Their reliability and relatively simple mechanical design made them well suited for wartime conditions.
Thousands of Harley-Davidson motorcycles were produced for military use during the war and were supplied to several Allied nations.
During the early years of the war motorcycles were widely used by armies because they were faster and more maneuverable than many military vehicles. Motorcycles could travel quickly across roads and narrow paths where larger vehicles could not operate easily.
Military motorcycles were commonly used by dispatch riders who carried messages between units. Before the widespread use of modern radio communications, these riders played an essential role in battlefield coordination.
Production Years: 1940-1945
Engine: 45 cubic inch side-valve V-twin
The Harley-Davidson WLA became the most famous American military motorcycle of the Second World War. The model was based on the civilian WL motorcycle but was modified for military use.
The WLA included several military-specific features such as blackout lighting, heavy-duty luggage racks, rifle scabbards, and protective skid plates.
More than 90,000 WLA motorcycles were produced during the war, making it one of the most widely used military motorcycles in history.
The WLC was a military version of the Harley-Davidson motorcycle produced specifically for the Canadian military. Although similar to the WLA, the WLC included several modifications designed to meet Canadian military requirements.
These motorcycles were widely used by Canadian forces during the war and also appeared in many Allied military units operating in Europe.
One of the most unusual Harley-Davidson motorcycles developed during the war was the Harley-Davidson XA. This motorcycle featured a horizontally opposed boxer engine and shaft drive system.
The design was inspired by the German BMW military motorcycles used by the Wehrmacht. The boxer engine layout improved cooling and allowed the motorcycle to operate more effectively in desert environments.
Although the XA performed well in testing, the project was eventually cancelled because military planners determined that lightweight military jeeps were becoming more practical for many military roles.
Harley-Davidson motorcycles were supplied to several Allied nations during the war. One of the largest recipients was the Soviet Union, which received thousands of WLA motorcycles through the Lend-Lease program.
These motorcycles were used by Soviet reconnaissance units and military dispatch riders on the Eastern Front.
Harley-Davidson motorcycles also served with American, British, and Canadian forces throughout Europe and the Pacific.
Dispatch riders were responsible for delivering orders and messages between military units. These riders often traveled long distances through dangerous conditions, including artillery fire and enemy patrols.
Because of this role, military motorcycles had to be extremely reliable and easy to repair in the field. The simple design of Harley-Davidson motorcycles made them well suited for this demanding task.
After the war many surplus Harley-Davidson military motorcycles were sold to civilians. These motorcycles became popular among returning soldiers and helped introduce a new generation of riders to Harley-Davidson motorcycles.
Today surviving WLA and WLC motorcycles are highly collectible historic machines. They are often restored and displayed at military history museums and classic motorcycle exhibitions.
