Yes you can, but there is fitment work involved and it is only suggested for those with fabrication and mechanical experience. When in doubt, take it to a professional to complete the job safely! Notes: We have test fit a springer on a 1986-2003 Evo Sportster frame, and the typical aftermarket springer will fit the neck of the frame. There are some clearances to adjust, such as when turning the springer lock-to-lock (fully side-to-side) there is a weld seam on the neck that may have to be addressed, and on some models the fork lock tab is in the way and would need to be cut off. Another important thing to check is that the bars and risers you would like to run clear the gas tank when turning the bars fully side to side. You may need to run a custom Sportster gas tank and/or change the style of bars or risers you are using to give proper clearance.
