====== Sportster Technical Menu ====== {{:techtalk:sp-technicalmenu.jpg|}} {{common:space100x5px.jpg?35|}}Below you can find a vast array of technical information about the\\ {{common:space100x5px.jpg?35|}}Sportster model motorcycle created by Harley-Davidson in 1957. \\ {{common:space100x5px.jpg?35|}}The information is divided into four sections:\\ {{common:space100x5px.jpg?200|}}[[techtalk:menu#ironhead_technical_categories|Ironhead Models (1957-1985)]]\\ {{common:space100x5px.jpg?200|}}[[techtalk:menu#evolution_technical_categories|Evolution Models (1986-later)]]\\ {{common:space100x5px.jpg?200|}}[[techtalk:menu#reference_technical_categories|Reference Material (All Years)]]\\ {{common:space100x5px.jpg?200|}}[[techtalk:menu#misc_resources|Misc Resources - Sportster Parts, Tech Bulletins, etc.]]\\ 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. Select the Miscellaneous Resources for information about resources that can be helpful to servicing and maintaining your Sportster. You'll find parts sources, service bulletins, recalls, manuals, etc. in this section.
