10. Harley-Davidson WLA

By the beginning of World War II, Harley had developed a foothold of sorts in the American Motorcycle Company. As such, when war threatened again Harley Davidson responded. This time, they modified a popular civilian model, the WL. And the new model was known as the WLA. It weighed an incredible 550 pounds and was powered by Harley’s infamous 45 inch flathead motor. Some thought it to be bulletproof and it practically was. The advantages of WLA bikes were, first and foremost, speed. However, they were also easy to maintain and work on in the field when need be. Besides, they could take a heck of a beating on the road. And while not configured for combat gear use, they did include a holster for everyone’s war favorite, the Thompson sub machine gun. More than 70,000 of these Harley’s were made during World War II, including several thousand that went straight to the Soviet Union. Oops!
