-Built under a U.S. Government contact during World War II only 1,011 of these unusual [[motorcycles]] were produced as the North African phase of WWII was almost over when the model was ready for production.  Together with the increased use of the Jeep, and the lack of interchangeability with other [[Harley-Davidson]] military models a major concern, the project was canceled. It features rear [[shaft drive]], a hand clutch with foot shift and special disc wheels for desert use. It was a very close copy of the German [[BMW]] and [[Zundapp]] machines.
-The U.S. Army also asked Harley-Davidson to produce a new motorcycle with many of the features of BMW's [[side-valve]] and [[Drive shaft|shaft-driven]] R71. Harley largely copied the BMW engine and drive train and produced the shaft-driven 750&nbsp;cc 1942 [[Harley-Davidson XA]]. This shared no dimensions, no parts and no design concepts (except side valves) with any prior Harley-Davidson engine. Due to the superior cooling of the [[flat-twin]] engine with the cylinders across the frame, Harley's XA cylinder heads ran 100&nbsp;°F (56&nbsp;°C) cooler than its V-twins.<ref>{{cite web|url=http://www.motorcyclemuseum.org/classics/bike.asp?id=71 |title=Motorcycle Hall of Fame Museum: 1942 Harley-Davidson XA |publisher=Motorcyclemuseum.org |date= |accessdate=2009-01-05}}</ref> The XA never entered full production: the motorcycle by that time had been eclipsed by the Jeep as the Army's general purpose vehicle, and the [[Harley-Davidson WLA|WLA]]—already in production—was sufficient for its limited police, escort, and courier roles. Only 1,000 were made and the XA never went into full production. It remains the only [[shaft-driven]] Harley-Davidson ever made.

-The '''[[Harley-Davidson]] XA''' was a twin, [[four-stroke]] Road [[motorcycle]] produced by [[Harley-Davidson]] in 1942. Claimed [[horsepower]] was 22.53 HP (16.8 KW) @ 4600 RPM.
-==Engine==
-A 77.8mm [[bore]] x 77.8mm [[stroke]] result in a [[displacement]] of just 740.0 cubic centimeters. Fuel was supplied via a sidevalves.
-==Chassis==
-It came with a 4.00-18 front [[tire]] and a 4.00-18 rear tire. Stopping was achieved via expanding brake (drum brake) in the front and a expanding brake (drum brake) in the rear. The front suspension was a  leading link while the rear was equipped with a pluger rigid. The XA was fitted with a 4.09 Gallon (15.50 Liters) fuel tank. The wheelbase was 57.48 inches (1460 mm) long.
