Harley Davidson 1942 XA

Harley Davidson supplied thousands of traditional 45° V-twin WLA and WLC models to the Allied military during World War II, but the company also produced a small number of BMW-style machines for the war effort. Although the WLA was a good all-around military bike, the US army asked Harley-Davidson to produce a shaft-drive machine and Harley turned to the enemy for inspiration. BMW’s R75 was virtually cloned and a test batch of 1,000 XA’s were produced, as were a batch of prototype shaft-drive Indians, the idea being that the better of the two bikes would be awarded a contract. Neither satisfied the army, which ordered extra WLAs instead, thus ending the XA’s brief life. The XA used a transversely mounted side-valve flat-twin cylinder engine, had shaft drive to the rear wheel, a four-speed gearbox, and plunger rear suspension. The XA was a prototype shaft-driven machine built for the US army that was ultimately only produced in limited numbers because of the success of the Willys Jeep as a battlefield vehicle. While it was built to the special specification of the US military, the arrival of the immensely successful four-wheel drive Willys Jeep changed the agenda as far as military motorcycle use was concerned, and only 1,000 XA bikes were ever made.
