Harley-Davidson Advertising of the 1940s
War split Harley-Davidson advertising in the 1940s into two different worlds. The decade opens with an 80-cubic-inch big twin posed against a red field. Two years later, the pages are asking riders to save gasoline, support military production and buy war bonds. By 1947 and 1948, the civilian motorcycle is back in the spotlight.
The 80 Twin Gets the Whole Page
The 1940 cover calls the motorcycle “The 80 Twin” and prints the 5.00 × 16 tire size. That is Harley-Davidson’s 80-cubic-inch side-valve big twin, represented in the U-series by the UH and ULH. The overhead-valve E-series remained a separate line, and the 74-cubic-inch FL followed for 1941.
The red field, isolated motorcycle and “Motorcycle Supreme” slogan give the big twin the whole page. Nothing else competes with it. This is the last image in the group before war changes the message completely.
War Takes Over the Advertising
The March 1942 ad turns motorcycle economy into a wartime argument. Military aircraft fly above “Keep ’Em Flying,” while the copy asks riders to conserve gasoline and oil with a Harley-Davidson. The dealer space and mail coupon are still there, but patriotism now drives the sale.
Harley-Davidson’s wartime work centered on the WLA, a military version of the civilian WL. Blackout lighting, an oil-bath air cleaner and a bracket for a machine-gun scabbard were among the changes made for service. The complete story is covered in the Harley-Davidson WLA history.
“Front Line Hero!” makes the next appeal even harder to miss. A rider charges through the dust while “Back Him Up With Bonds!” tells the civilian reader exactly what to do. The motorcycle is no longer selling a weekend ride; it is carrying the whole war-bond message.
The Enthusiast kept riders in uniform connected with clubs and readers at home, while Harley-Davidson’s wartime production earned the Army-Navy E Award three times. The company’s advertising, motorcycles and factory were all working toward the same job.
Civilian Motorcycles Take the Page Back
“The World’s Finest Motorcycle” puts the civilian machine back on display. The studio treatment is clean, the front wheel fills the foreground and the rider looks ready for peacetime roads. The spring fork places it in the final years before the 1949 Hydra-Glide. The 1948 factory brochure shows the civilian range just before that front-fork change.
“The Mighty Harley-Davidson” and “World’s Most Popular Motorcycle” keep the postwar confidence turned up. The rider is relaxed, the motorcycle is clean and desirable, and none of the wartime urgency remains.
Harley-Davidson introduced the Panhead engine for 1948, then added the hydraulic front fork for 1949. The 1936-1947 model reference covers the Knucklehead years that carried the company through the war. By the end of these five advertisements, Harley-Davidson has gone from prewar pride to military duty and back to selling the motorcycle people had been waiting to ride.
