During World War II, motorcycles played a crucial role in communication and transportation. Some of the most widely used models were the BMW R75 and Z├╝ndapp KS 750 by the Germans, the Harley-Davidson WLA and Indian 841 by the Americans, and the Norton 16H by the British. These bikes were specifically designed for rugged conditions and were often equipped with sidecars for additional cargo or personnel. They were known for their durability, reliability, and ease of repair. It's fascinating to see how these two-wheeled machines were a vital part of the war effort.
