Below is a detailed year‑by‑year look at the most significant gas tank emblems, the styles that defined each era, and practical tips for identifying genuine parts.
History of Harley Davidson Gas Tank Emblems
The first Harley‑Davidson motorcycles, produced in 1903, featured simple stamped steel tanks with little more than the company name etched into the metal. As the brand grew, the need for a distinctive badge became apparent, leading to the introduction of separate emblems that could be riveted or screwed onto the tank. Early emblems were often made of brass or nickel‑silver, giving them a warm, vintage patina that many collectors prize today. Think about it: throughout the 1920s and 1930s, the company experimented with enamel fills, raised lettering, and circular logos that echoed the burgeoning art‑deco movement. In real terms, post‑World War II, Harley‑Davidson embraced chrome plating and bold, block‑letter designs that matched the aggressive styling of the new “Knucklehead” and “Panhead” engines. The 1960s and 1970s saw a shift toward simpler, more graphic symbols—most famously the bar‑and‑shield logo that remains the cornerstone of the brand’s visual language. In recent decades, limited‑edition models have revived heritage emblems while incorporating modern finishes such as matte black, brushed aluminum, and even LED‑lit accents.
Emblem Evolution by Decade
1900s‑1910s: The Pioneering Years
- 1903‑1905: No separate emblem; the tank bore a stamped “Harley‑Davidson” script.
- 1906‑1910: Introduction of a small brass oval badge reading “Harley‑Davidson Motor Co.” with the founding year “1903” beneath.
- 1911‑1915: Transition to a rectangular nickel‑silver plate with raised block letters; early models used two‑piece construction (background plate + letter insert).
1920s‑1930s: Art‑Deco Influence
- 1920‑1925: Circular enamel emblem featuring a red background, white “Harley‑Davidson” script, and a black bar‑and‑shield inset.
- 1926‑1930: Shield‑shaped badge with a chrome rim, red enamel fill, and silver lettering; often paired with a small “V‑Twin” insignia on the side.

1940s‑1950s: War Era and Post‑War Boom
