Harley-Davidson WLA Classic Motorbikes for Sale

History of the Harley-Davidson WLA

The Harley-Davidson WLA was specifically developed for military use during World War II, based on the WL civilian model. The motorcycle's 45-cubic-inch (740 cm³) side-valve V-Twin engine and its rugged construction made it a reliable asset for the US Army. Nicknamed the 'Liberator' in Europe, the WLA became synonymous with Allied advances through the continent, often seen escorting convoys, carrying couriers, and providing essential mobility in rough field conditions. Its influence extended well beyond army use, with surplus examples returning home and finding new life amongst civilian riders and collectors.

Model History of the WLA Series

Harley's WLA followed the WL civilian bike and was specifically tailored for wartime needs, with military equipment and adaptations such as olive drab paint, blackout lights, and extra rugged mechanicals. The WLA was continuously produced through the war years, and post-war, many units were sold as surplus. The predecessor was the WL, and there was no direct successor in the post-war military context, although Harley's military and civilian V-Twin tradition remains integral to the brand's legacy.

Highlights of the Harley-Davidson WLA

The WLA features a foot clutch, a three-speed hand shift gearbox, a robust steel frame, original 6-volt electrical system, and period accessories such as military sirens and blackout lamps. Typical configurations include authentic olive drab paintwork and drum brakes front and rear. Many surviving examples have either been kept as historically accurate restorations or preserved in original military specification.

Technical Data

Special Editions and Collectible Models

Many WLAs were customised for specific military branches, featuring details like special cargo racks, additional toolboxes, or alternative lighting. Post-war, some units were modified for police or civilian use, but the most collectible are those remaining close to original US Army spec with period-correct accessories.

Weak Spots and Common Issues

Routine issues for the WLA include wear to the manual gearbox, oil seepage from the classic flathead engine, and corrosion on military paint due to age. The electrical system, being 6V, is less reliable by modern standards, and care is needed when sourcing authentic replacement parts, especially for original military fittings. Drum brakes require precise adjustment and regular inspection for consistent performance.

Engine and Performance, Transmission and Handling

The 45-cubic-inch V-Twin delivers modest power and robust torque, designed for durability over outright speed. The hand shift and foot clutch setup rewards the methodical rider, while wide handlebars and a rigid frame offer stability off-road or on poor surfaces. Handling is predictably heavy due to military equipment, but delivers period-correct charm for those used to pre-unit machines. The 1942 WLA is a frequently encountered variant, celebrated for its role in the Second World War and typical of the series in both configuration and historical value.

Interior, Comfort, Exterior and Design

The WLA's design revolves around function: olive drab or military green paint, minimal bodywork, sprung solo seat, military accessories such as blackout lights, and robust steel components. Interiors are utilitarian, with focus on reliability under tough conditions. Accessories range from ammunition boxes to military racks, and many WLAs preserve factory markings, adding to authenticity. Later restorations often strive for meticulous accuracy, sourcing correct wiring, sirens, and period fittings.

Other Noteworthy Features

Harley-Davidson WLAs sometimes feature post-war modifications: civilian paint, conversion to 12V electrics, or civilianised fender trims. However, most sought-after examples remain true to military origins, complete with original tags and military paperwork if available.

Summary

The Harley-Davidson WLA offers collectors an unparalleled connection to military motorcycling history. Its robust mechanics, historically accurate restorations, and unique wartime provenance set the WLA apart in the world of classic motorcycles. With all supply and demand in its segment, the WLA remains a singular presence among vintage Harley-Davidsons.
