Sportster Technical Menu
Below you can find a vast array of technical information about the
Sportster model motorcycle created by Harley-Davidson in 1957.
The information is divided into three sections:
Ironhead Models (1957-85)
Evolution Models (1986-later)
Reference Material (All Years)
Click on a section above or simply scroll down the page to review the technical categories that are available.
Select the Ironhead or Evolution sections for year specific information. For general subjects pertaining to all Sportsters,
select the Reference section. Because there is some overlap in technical information between the Ironhead and
Evolution models, if you don't find what you are looking for in one section you might want to explore the equivalent
category in the other model section.
