1985 Sportster

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⁾

17 Digit VIN for 1985 Sportsters
Origin	Make	Weight Class	Model	Engine Size	Intro Date / Special Models	VIN Check Digit	Model Year	Assembly Plant	Serial Number

Example VIN on Frame Reads: 1HD1CBH15EY112016
1	HD	1	CA	H	1	6	F	Y	112016
Example Abbreviated VIN on Case Reads: CAHF112016
			CA	H			F		112016

Engine Serial Numbers

The engine numbers changed and are no longer stamped the same as the frame. This change is part of the new 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)

Specifications

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.
