If you have a shorter VIN, check it again and copy it correctly. If the VIN is less than 17 characters, then it is most likely from a vehicle built in 1981 or earlier. NHTSA required all vehicles manufactured in 1981 to be assigned a 17-digit VIN.
How to Find the Vehicle’s VIN Number?
The VIN (Vehicle Identification Number) is indicated in vehicle title, registration, and insurance documents. Most, if not all, online marketplaces for cars require sellers to post with the VIN so you can do a VIN lookup quickly.
Here are some common VIN locations on the car:
- Under the hood (engine block)
- Dashboard (near the windshield)
- Door frame (left-hand inner wheel arch)
- Driver’s side door (near door jamb)
- Some cars may have it on the firewall, steering wheel, and radiator support bracket.
How to Decode the Vehicle Identification Number (VIN)?
Tap into the wealth of data available on millions of vehicles. Each vehicle gets a fixed ID number in the production line called VIN. It is the most reliable way to get vehicle information. Databases managed by auto makers and US vehicle registration agencies carry the VINs. VinCheck.info works with these entities to update vehicle information into its own database.
Each section of the VIN has a different meaning. It is based on 1979 and 1980 ISO standards. Please refer to the diagram below for the matching value of each character or section.
According to the Society of Automotive Engineers, Code of Federal Regulations, the VIN has seven sections describing the following:
- where the vehicle was built (1st character)
- who made the vehicle (2nd and 3rd characters)
- basic description (4th to 8th characters)
- whether the VIN was authorized (9th character)
- model year (10th character)
- where the vehicle was assembled (11th character)
- serial number (12th to the 17th characters)
Flexible fuel vehicles can be identified by the 2nd, 3rd and 8th characters.

What is VIN Cloning
Not all VINs accurately represent a car’s true identity. A car may have a VIN that actually belongs to another car. VIN cloning is a crime that involves replacing the VIN of a stolen car or a car with a bad history with the VIN of another car of the same model and make. Its goal is to misrepresent or hide the identity and history of a car usually offered for sale. First, the factory-installed VIN plate is pried off and then replaced with a legitimate VIN. With fake ownership documents, the car with the cloned VIN can be easily registered in another state.
Here are the red flags that can point to VIN cloning:
- Price is significantly cheaper compared to cars with similar make and model.
- VIN plate may show signs of tampering.
- VIN lookup results and actual vehicle documents may be inconsistent.
- Vehicle inspection observations are not consistent with documents and VIN decoder findings.

Serial and Other Numbers
Identifying your K Model or Sportster requires looking at a lot of numbers to determine what year the motorcycle is, and whether many of the parts are original to the bike. The following descriptions of 'numbers' applies specifically to Ks and Sportsters, and in general to all Harley-Davidsons up to 1969.
A Word About Years
There are two kinds of years we'll be dealing with here. First, there's the calendar year, which runs from January 1 to December 31. Then there's the automotive model year, which runs from September 1 to August 31. Since the beginning of time, car, truck, and motorcycle manufacturers have introduced their shiny new models after summer's over, and people are heading back to work and school. This is four months – one-third of a year – ahead of the calendar year!
The first 1960 model year motorcycle that appeared on the dealer's showroom left the factory around September 1, 1959. The individual parts, particularly basic things like engines and frames, were often made a month or two ahead of time. So that first 1960 may have parts manufactured in July or August 1959.
When we speak of a change occurring during early/mid/late year, we are referring to the model year. In some cases, it is possible to narrow it down further than that, but in most cases it isn't. If we really have no idea, we will use “sometime during the year”. Other books and websites often use “mid-year” to mean “sometime during the year”, but we'll try to reserve the term “mid-year” to really mean “middle”.
Motor Seral Number (“VIN”)
Almost every vehicle ever made has a manufacturer's serial number located somewhere on it. There was no industry standard, so each manufacturer made up their own numbering scheme, and affixed it to the vehicle wherever it wanted. In 1981, the U.S. Department of Transportation mandated a standard 17-digit Vehicle Identification Number (VIN) scheme, and for motorcycles, mandated the VIN be affixed to the frame. But before that…
From the early days, up to and including the 1969 model year, Harley-Davidson stamped the serial number of a motorcycle into the left engine case. The frame did not have a serial number. The serial number followed the code:
YY MMMM SSSSS | 62 XLCH 2373 | |
YY | – a two character (numeric) model year, last two digits | 62 |
MMMM | – one-to-four character (alphabetic) model designation | XLCH |
SSSSS | – a four or five character (numeric) production sequence number | 2373 |
The production sequence number gets complicated.
Before 1960, the sequence number started with either 1000 or 1001 - NOT 0001. Although the common wisdom has long been 1001, there have been a few documented cases of a serial number 1000 uncovered. We will use 1000 through the remainder of this article.
The sequence number runs with the basic motorcycle model, not the different variants. Dubstep youtube. So the first few 1959 Sportsters might have been numbered 59 XLH 1000, then 59 XLCH 1001, then 59 XLH 1002, then 59 XLCH 1003…
From 1960 through 1969, Harley started an unusual odd/even scheme. In years ending with an even number (example: 1960), the sequence numbers ran 2000-2999, then skipped to 4000-4999, then 6000-6999, then 8000-8999, then 10000-10999, then 12000-12999. In years ending with an odd number (example: 1961), the first digit of the production number was always odd. So it ran 1000-1999, then skipped to 3000-3999, then 5000-5999, etc.
Why? One theory is that this was an anti-VIN-forgery scheme. The other theory is this was a nefarious scheme to make people think production was much higher than it actually was, to mask Harley's low sales figures in the 1960's.
The font used for the VINs varied over the years. Here are some photographs of serial numbers.
When Was My Bike Produced?
The serial number was applied late in production, close to the factory door. Historian Jerry Hatfield researched monthly production figures at the Harley-Davidson archives, but found they varied 'all over the place'. Normal production scheduling required things to be made in batches. Sales might not have matched the factory's predictions, so they might have had to catch-up by increasing production of one model while slowing production of another. Harley's book, The Legend Begins, provides annual production figures. Dividing the total production by 12 months can give you a best-guess as to what month your bike was produced, but this will not be truly accurate.
Note: the 1952 K model was late to market. It was was unveiled for the first time to the dealers in Milwaukee at their November 1951 convention.

Motor Belly Numbers
This section is undergoing revision
'Belly numbers' are stamped into the bottom of each crankcase half. The crankcase halves were cast, mated in pairs, line-bored for the crankshaft, and then numbered to ensure they remained a mated pair. The same sequence number was stamped into each crankcase half. The numbers should match each other, but they will NOT match the serial number of the engine. The code is: MYY SSSSS | 761 3334 | |
M | – one-character (numeric) the model designation (See below) | 7 |
YY | – two character (numeric) model year, last two digits (See below) | 61 |
SSSSS | – a four or five character (numeric) mating sequence number | 3334 |
The M model designation is '5' for K models and '7' for Sportsters.
The YY is the model year that the crankcase halves were mated. This is usually the same as the model year of the bike. However, if you have a very low motor serial number, your belly numbers may have a year code one year below the model year. In some years, the factory mated too many case sets, and then used them up early the following year.
An oddity is that all 1952 K models have 552-XXXX, and all 1957 Sportsters have 757-XXXX belly numbers.
SSSS[S] is a four or five character (numeric) sequence number. Usually, the SSSS of the belly number is within +/- a few hundred of the SSSS of the un-coded VIN, but this is not always the case. We are actively researching this area. The important thing is that the belly numbers match, and the year code is plausible.
Here are some photographs of belly numbers.
Frame Date Codes
Most K and Sportster frames have a date code stamped into the frame. It is on the right side, in the area where the rear gas tank bolt goes through the frame – for the large tanks. On Ks and XLHs, it is under the right rear tank ear, so you can't see it with the tank on. On XLCH with the small tank, it can be seen with the tank on.
M Y | H 1 | |
M | – one-character (alphabetic) month code (See below) | H |
Y | – one-character (numeric) year code, last digit | 1 |
The month code is as follows: A=January, B=February, C=March, D=April, E=May, F=June, G=July, H=August, I=September, J=October, K=November, L=December
The year code is the last digit of the calendar year the frame was produced.Frames were typically produced a month or two before they were used. So a low VIN number bike will have a date code from the previous year. 1952 K model frames do not have date codes, and only the last few months of 1953 had them. See the Technical article on Frames for more information.
Here are some photographs of frame date codes.
Frame Security Codes
1962 through 1969 frames had a Security Code, sometimes known as an Anti-Theft Number, which was stamped into the frame neck. On Sportsters, it was sometimes stamped on the left side, sometimes on the right side. (On Big Twins, it was on the left). The factory used this code to respond to police inquiries, but exactly what it identifies is unknown. The code had the format YNNN or YNNNN where Y was a letter designating a year or year range, and the Ns were three or four numbers. The code will be hard to see if the paint on the head is thick.
![Serial Serial](https://www.hdforums.com/forum/attachments/primary-transmission-driveline-clutch/328716d1376533834-can-t-identify-5-speed-transmission-transrear.jpg)
Y NNN or Y NNNN | D 1234 | |
Y | – one-character (alphabetic) year code (See below) | D |
N | – one-character (numeric) digit | 1 |
This code chart comes from Bruce Palmer's book How To Restore Your Harley-Davidson on Big Twins. It generally applies to Sportsters also, however one very early 1970 XLCH frame examined did not have a Security Code. While the 1970 Big Twin frame had both a VIN pad and a Security Code, it is believed the new frame introduced for the 1970 Sportster had only the VIN pad, and did not have the Security Code.

J | 1968 – 1969 |

Here are some photographs of frame security codes.
Part Numbers
Every Harley-Davidson part has a part number assigned to it. Part Numbers are shown in the Spare Parts Catalog, but only in rare instances do these ever appear on the actual parts, and then they are typically painted, to help the retail dealer quickly identify them in his spare parts stock. Some wheels, fenders, and chainguards have the part number painted in an inconspicuous place.
Harley Transmission Serial Number Location
BBBBB-YYS | 34961-57 | |
BBBBB | – five character (numeric) base part number | 34951 |
YY | – two character (numeric) year of first use | 57 |
S | – optional one character (alphabetic) Suffix | n/a |
The 'year of first use' typically, but not always, is the first year the part was used. However, in some instances, particularly with the first year of a new model, YY may be one year prior.

The Suffix indicates a minor revision. Parts with a Suffix letter replace, and will physically fit on models back to the YY, but they are different than the non-suffix parts, sometimes in a very minor way, but sometimes in a major way. The first revision gets the letter 'A'. Subsequent revisions get 'B', 'C', etc.
The suffix can also be 'R', indicating a Racing part.
Casting Numbers
Most of the cast aluminum and forged steel parts have a raised “casting number” cast/forged into them. This number has the same format XXXXX-YY as a part number, but you will never see this part number in a Spare Parts Catalog. The reason - it is an factory internal use only part number. Why would there be such an animal?
Harley outsourced aluminum castings and steel forgings. Harley did extensive machining and fabrication, but the castings and forgings required specialized manufacturing capabilities that were cheaper to buy than to build. For inventory reasons, Harley had the outside supplier cast/forge an internal use only part number into the “raw material” part.
Most castings required machining before becoming an actual part. The raw material Footrest support (left), which has casting number 50950-52, was drilled and tapped to become part number 50951-52.
Many 'parts' are built from 'sub-parts', so the casting number does not identify the part. A K-model Saddle bar (“seat tee”) is a good example. The 1952-1953 Saddle bar (Part# 51902-52) uses the outsourced front section (casting #51910-52) with an in-house made rear section. The 1954-later Saddle bar (Part# 51902-54) uses the same front section, but with a different rear section. To confuse matters, around 1959, the front section changed slightly (now casting# 51901-52A), but the Saddle bar's Part# 51902-54 did not change.
So casting numbers do not identify parts. But they can be important clues to the version, or production date, of a part.

Casting Date Codes
Some parts, particularly the cast engine crankcases, covers, and cylinders, have date codes cast into them. These are usually the month and year, but their use, and format, are inconsistent. There are also many miscellaneous casting marks, which might indicate the foundry, or some production sequence.
Here are some photographs of engine casting date codes.
Cylinder Date Codes
Transmissions For Harley Davidson
The cylinders were date code marked at the base to denote the casting date of the cylinder. There is a capital letter (“I” omitted) which identifies the month of the casting. Then there is a small plate fastened with screws. On the plate are two groups of digits separated by a dash. The first group of one or two digits is the day of the casting and the second group is the last digit of the year.
Cylinders cast in 1957 to 1961 have the part number cast on both sides of the cylinder base and 62 and later have it cast on the spark plug side only. Early 1957 cylinders have the date code on the spark plug side and later 57 cylinders have them on the push rod side. The earlier cylinders are a harder casting material than those with the date codes on the push rod side. The cylinder date codes can precede the bike manufacturing date by anywhere from two to eight months.
K/KH Left Engine Cases - The Letter D
K or KH left engine cases with the letter “D” stamped near the serial number denotes that the case was a replacement case (made in 1957 or later, or perhaps refurbished existing stock) that was redesigned to use the Sportster 34844-57 transmission access cover. The original K/KH case and access cover used cone-shaped dowels. The replacement “D” case has straight dowels, and requires that the -57 access cover be used with it.
