Harley-Davidson Motorcycle VIN Lookup & Decoder Chart

How to Determine Which Year & Model Harley You Own

The first step to getting the right parts and modifications done to your motorcycle, is knowing what you have. If you have ever walked into your local auto parts store, you know this to be true. As soon as you ask for a particular part, the clerk behind the counter starts the rapid-fire questions that help determine what you actually have.

For modern vehicles, identifying this information is straightforward—typically found on the driver’s door. However, Harley-Davidson motorcycles require a different approach. These bikes are stamped with unique identifiers and VINs, and the location of these Harley VIN codes has evolved over the years. By using a Harley-Davidson VIN decoder or Harley VIN lookup tool, you can retrieve details like the year, model, and even specific attributes of your bike.

Vintage Harley-Davidson VIN Numbers & Locations

The very early models 1903-1909 did not have a stamping for identification. The very first Harley Davidson models were simply identified by what they were. It’s not like in today’s world, where you’re navigating a wide array of models and options, making a motorcycle tire size comparison essential.

In 1910 the practice of stamping the motor was implemented. The bike model was identified by the 6, 6A, 6B, 6C, 6E and then the series number which was a range between 4200-7600.

This was the first year to feature the belt idler and the HD bar and shield logo with the word “trademark.” This same method was applied to all bikes moving forward until the late 1960s, marking a notable point on the Harley-Davidson cc engine list.

Harley-Davidson Anti-Theft Codes

In 1962 Harley-Davidson started stamping anti-theft numbers on the left side of the neck, in addition to other places such as triple trees, and transmissions. The anti-theft number starts with a letter and is followed by four numbers. These were tied to a VIN and were an effort to help identify stolen motorcycles or parts, however, they are not a VIN themselves and are not used for titling a motorcycle.

What Year Did Harley Start Putting A VIN On The Frame?

1970. The 1970 model year motorcycles were the first that had a matching VIN number on the frame that corresponded to the VIN found on the engine of the bike.

The Harley-Davidson VIN Code Decoder

1930 - 1969 Harley-Davidson VIN Decoder

From 1930 to 1969 the VIN’s on Harley-Davidson Motorcycles were sorted as follows (from left to right):

The first two numbers designated the year of the motorcycle. The following letters represented the models, and the last numbers are the production numbers.

Models built from 1930 to 1969:
G , GE - Servi Car Side valve 45 cubic inch three-wheeler, 1932 to 1972
E , EL - Overhead valve 61 cubic inch
F , FL - Overhead valve 74 cubic inch
K - Side valve 45 and 55 cubic inch
U , UL - Side valve 74 or 80 cubic inch
V , VL - Side valve 74 cubic inch made prior to 1936
W , WL - Side valve 45 cubic inch made 1934 to 1952

1970 - 1980 Harley Davidson VIN Decoder

In 1970, things get little more complicated. The addition of new models and the involvement of the government pushed Harley to come up with a different system that includes codes that represent a model.

These 9-character alpha numeric VIN codes are stamped on both the engine and the frame. The first two characters represent the model code. This is a number and alpha character.

This 1972 XLCH 1000 you can find the vin on the right side of the frame. 4A19006H2
4A = XLCH-1000
19006 = production number
H2 = 1972

The next 5 digits represent the production numbers, and the last two characters represent the model year. This is an alpha numeric code. This is the system that was used from 1970-1980.

NOTE: In 1979 there was a small collection of bikes that were produced with non-conforming engine numbers. The factory caught the issue but not before some of the bikes were out on the market. The production range from 1/9/79 to 2/7/79 has VINs in the range from 43000H9 through 48199H9. These were the only exceptions during this time period.

1981 - 2000 Harley Davidson 17 Digit VIN Decoder

In 1981 Harley moved to a 17-digit VIN code. The full VIN was stamped on the neck of the frame, and an abbreviated version of the code was stamped on the engine. This code and sequence remained unchanged through the year 2000.

An example of this code would look like this: 1HD1BFK11BY127956

• The first digit represents where the bike was made. 1 = USA
• The following HD represents Harley-Davidson.
• The fourth digit represents the weight class. 1 = Heavy Weight, 4 = Light Weight, 8 = Sidecar.
• The next two characters represent the model. (see Model Code Chart below).
• The 7th digit represents the engine type (see Engine Codes Chart below).
• The 8th digit represents the introduction date. 1 = Regular,  2 =Mid-year, January, 3 = California Special, 4 = Daytona, March
• The 9th digit is a check digit. If you don’t know what a check digit is, it is simply a digit to make sure the entire string is valid.
• The 10th digit is the year of manufacturer.
• The 11th digit is the assembly plant the bike was made in. Y = York, PA, T = Tomahawk, J = Milwaukee, K = Kansas City.
• The 12th to 17th digits are the production numbers.

So, there you have it. As you can see with the implementation of the 17-digit codes, you will need a reference to define what those codes represent. We hope you can use this article as a reference so you can determine all the details for the bike in question. Enoy!
