You’ve seen them at every stoplight and dive bar—those little pieces of jewelry bolted or glued to the side of a gas tank that tell you exactly what you’re looking at. Or do they? Honestly, if you’re trying to identify a bike just by the metal on its side, you’re playing a dangerous game. Harley Davidson tank badges by year are a chaotic map of the brand's history, and they aren't always as straightforward as a VIN.
Collectors go crazy for these things. A genuine 1930s bird scroll can cost more than some people's first cars. But here’s the kicker: Harley didn't even use badges for the first few decades. They used paint. They used decals. Then they used plastic because it was "the future." Basically, the evolution of the emblem is the story of the company itself—struggles, anniversaries, and corporate takeovers included.
The Early Days: When Paint Was Enough
From 1903 all the way through 1932, the concept of a "badge" didn't really exist in Milwaukee. You had simple, clean lettering. It was very Victorian, very "workshop." Most people think the iconic Bar and Shield was always on the tank, but that's a myth. While the logo was born around 1910, the gas tanks usually just featured "Harley-Davidson" in a variety of blocky or serif fonts.
Everything changed in 1933. The Great Depression was hitting hard, and sales were, frankly, miserable. Harley needed a spark. They introduced the Bird Scroll. It was this ornate, bird-like flourish surrounding the name. It was flashy. It was desperate. And it worked.
Then came the Flying Diamond in 1934 and 1935. It was pure Art Deco. If you find an original tank with this design, you're looking at a piece of history that survived the transition from the flathead era to the dawn of the legendary Knucklehead.
The Metal Revolution (1936–1950)
1936 was a watershed year. The EL "Knucklehead" arrived, and with it, a compact, stamped metal design that felt like the future. This was the first time the brand really committed to a dimensional look.
- 1940-1946: This was the first "true" metal badge. Because of World War II, metal became a scarce resource. Harley actually had to stop using these for a bit or simplify them significantly. If you see a bike from '43 with a massive chrome badge, somebody likely added that later.
- 1947-1950: The Speedball. This is arguably the most famous vintage design. It’s that red and chrome circle that looks like it’s moving while standing still. It bridged the gap between the last Knuckleheads and the first Panheads.
The Weird Mid-Century Shifts
By the 1950s, Harley was celebrating. 1953 marked the 50th anniversary, and they went all out with a V-shaped medallion. It honored the V-Twin engine, which by then was the company's soul. "50 Years" was stamped right on top.

You’ve gotta love the 1961-1962 "Gun Sight" badge. It’s weird. It’s basically a target or a sight from a rifle. It didn't have much lettering, which was a bold move for the time. Some riders hated it because it felt too "military" or just plain confusing, but today, it’s a cult favorite for restoration projects.
Then plastic happened. In 1957, the Sportster was born, and with it came the first plastic emblems. They were round and, honestly, a bit cheap-feeling compared to the heavy cast-iron or zinc badges of the 40s. But hey, it was the 50s—plastic was high-tech back then.
The AMF Era: The Badge Everyone Peeled Off
If you want to start a fight at a vintage bike show, mention AMF. In 1969, American Machine and Foundry bought Harley-Davidson. From 1972 to 1981, the tank badges often featured "AMF" prominently.

Purists hated it. They felt the quality had dipped, and the corporate logo on the tank was an insult. It was a common ritual for new owners to buy a bike and immediately heat up the badge with a hairdryer to peel it off. Because of this, original, pristine AMF-era tanks are actually becoming quite rare. They represent a gritty, polarizing time in the company's history that people are finally starting to appreciate.
Modern Times and the "Jewelry" Phase
After the 1981 buyback, when the "Thirteen" executives took the company back, the badges returned to their roots. The 1982 Bar and Shield return was a statement of independence.
Since the 90s, badges have become incredibly detailed. Take the 1995 Bad Boy. It had an enameled badge that looked like it belonged on a necklace rather than a motorcycle. It was the start of the "jewelry" era, where CVO (Custom Vehicle Operations) bikes began getting massive, three-dimensional eagle heads and heavy chrome slabs.
The 100th Anniversary in 2003 was another massive milestone. That winged badge is everywhere. If you’re looking at a 2003 bike, it better have that specific silver and black emblem, or something is seriously wrong.
How to Tell if a Badge is Real
Since there are so many "repop" (reproduction) badges out there, identifying an original is a bit of an art.
- Check the backing. Early badges were often screwed into the tank. Modern ones (post-60s) are almost always held on by 3M adhesive tape. If you see screws on a 2010 Street Glide, it's either custom or a cover-up.
- Look for the embossing. On some years, like 1961, the tank itself was actually embossed in the shape of the badge. You can feel it from the inside of the tank if you’re brave enough to stick a finger in the fill hole (drain the gas first, obviously).
- The Weight. Modern plastic badges are light. The old stuff is heavy. If you tap it and it sounds like a Lego brick, it’s either a newer model or a cheap replacement.
Your Next Steps for Identification
If you're staring at a "mystery" tank and trying to figure out if those Harley Davidson tank badges by year are accurate, don't just trust a Google image search. Go to a site like Lowbrow Customs or the Harley-Davidson Museum's digital archives. They have the specific part numbers and measurements.

Measure the width of the badge. A 1955 badge might look like a 1956 one to the naked eye, but the dimensions and the "V" depth are slightly different. Also, check for a small copyright date or part number stamped on the bottom edge or the backside—this is the smoking gun for authenticity. If you're buying a vintage tank, always look for the "witness marks" of where the original badge sat; if the fading doesn't match the shape of the badge, you’re looking at a project bike, not a survivor.
