Vehicle Identification

Frame VIN Numbers

The only numbers used for the purpose of identification are on the right neck and frame downtube.

  • The frame is stamped with a Vehicle Identification Number (VIN) identification.
  • There are still other stampings on the different parts of the frame combined with certain features that can be used to date the frame.
    But the only numbers used to identify the entire bike for ownership purposes is the VIN number stamped in the right side neck.
  • In addition to the neck VIN, an identification label is located on the frame giving the VIN and date of manufacture.
    This label was required by law for identification.1)

In 1981, the full VIN was expanded to include country of origin, maker, bike weight, engine displacement, introduction date, a check digit and which factory made it 2).

  • This new nationwide system is designed to provide improved theft protection and more specific vehicle information to HD and government agencies.
  • In addition to the neck VIN, an identification label is located on the frame giving the VIN and date of manufacture.
    This label was required by law for identification.3)

Engine Serial Numbers

The engine numbers are no longer stamped the same as the frame. This change was part of the 17 digit VIN system.
The serial number is stamped on the case, right side, between the cylinders but is not used for identification purpose of ownership.

  • An abbreviated version of the 17 digit VIN is stamped into the engine case. It's the exact same as the frame numbers but certain designations were left out.
    (including country of origin, maker, bike weight, intro date, check digit and plant of origin)

Related Manuals and Documentation

Below are some suggestions for manuals for your ride.
You should have, at minimum, a Factory Service Manual (FSM) and a Factory Parts Catalog for your year model.

Factory Service Manuals (FSM);
The FSM will have the most accurate information, procedures and specs.
Clymer and Haynes make service manuals also for Sportsters but some of the information is in error to the factory FSMs.
And some of the information in the aftermarket manuals is vague in information or procedures but they may have more pictures.
So it is generally said you can get use from both an aftermarket manual and the factory service manuals but get the factory manual first.
Click Here to view the Factory Service Manual page in the Sportsterpedia.

Parts Catalogs;
The Parts Catalog has part numbers of course but it also has exploded parts views.
And some of the exploded views are confusing or not related to each other on the same pages.
But, all in all, the exploded views do help finding what goes where.
Most of the fasteners listed in the relevant parts catalog individual pages have thread sizes and lengths also in case you need those.
Below is a simple list of original and “latest edition parts catalogs. The in-between year books may show different part numbers for the same year model bike.
Click Here to see the Factory Parts Catalog page in the Sportsterpedia for parts catalog uses and a full list of parts catalog numbers from 1957 to present.
(complete list of other parts catalogs and supplement catalogs that pertain to each year model on the bottom of that page)
Some often acquire several year model parts catalogs and that page will help you decide which ones are right for you.

The Ironhead Multi-Year Parts Catalog Curse

Below is a summary of an article on the Sportsterpedia Parts Catalogs page regarding parts book errors.
You can also read the full article from this link: The Ironhead Multi-Year Parts Catalog Curse.
Due to all of the errors and non corrected editions, it's always a good idea to acquire several year parts catalogs surrounding your year model.
Which year catalogs you'll need will depend on many factors but the main Parts Catalog page in the Sportsterpedia will help you decide which ones you need.
Click Here to see the Parts Catalog page. A full chart of all the parts catalogs made for Ironheads is at the bottom of the page.

  • Not all multi-year catalogs will list factory installed parts on your bike.
  • You may need several year catalogs to determine factory installed parts for your year model.
  • Some parts first appeared or only appeared in Parts Supplements, Service Bulletins or other literature
  • Later catalogs may show parts for older models that were never factory installed on them.
  • Some catalogs have missing parts and/or missing models in some parts listings.
  • Some illustrations do not have a part number listed.
  • Drawings may or may not look like your part number.
  • Some exploded parts diagrams show the assembly in the wrong order or missing pieces.
  • There may be misleading information about parts that fit your year model.
  • Fastener lengths and thread pitch may change depending on catalog used.
  • The MoCo knew about and tried to correct at least some of the parts catalog mistakes.

Model Designations

  • Model Designations: XLH-1000, XLS-1000, XLX-1000 (XLX-61)

The 57-69 service manuals and other literature from HD cover multiple years.
And the 1957-1959 “XL” is included with the information in these manuals up through 1969.
However, the 1970-1978 FSM also includes an “XL” model in the specs but does not refer to the 57-59 XL motorcycle.
Starting in 1977, there were also XLT and XLCR models (these are both included in the “XL” verbiage).
The “XL” noted in 1970 and future literature simply refers to a street legal “Sportster” model motorcycle.
The last XLCH was made in 1979 but both “XL” and “XLH” verbiage was used in manuals and literature up through the 2003 manuals.
(referring to the same bikes).
“XLH” became the mantra for the base 883cc model but the manuals also refer to XLH1100 and XLH1200 Sportsters.
1979-1985 service manual is titled for XL/XR models and the specs in are listed for XLH, XLCH and XLS models.
2004-up manuals dropped the “H” altogether. So 2003 is the last year the MoCo referred to a Sportster as an XLH.
