Vehicle Identification

Frame VIN Numbers

Starting in 1970, 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.5)
  • The serial number is the 3rd through the 7th digit. All serial numbers run consecutively regardless of model year. 6)

Related Manuals and Documentation

See the Navigation menu on the upper left of this page.
From there you can go to the main Ironhead section menu, the Reference section for general and in-depth procedures, and the Misc Resources for 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.

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.

The Parts Catalog has part numbers of course but it also has exploded parts views.
However, IT IS NOT INTENDED TO BE AN ASSEMBLY MANUAL.
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.
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.
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

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.
