Sorry I don't know for sure if they will bolt up, but BikersDream or Strokers might be able to tell ya. I know I bought my sissy bar from on 06 owner, so not a lot changed over the years. The 300 tires need the 14" wide sissy bars, and the 250's I believe are 12" wide, but as far as the struts go they may be the same. Sorry I can't say for sure on fitment, just trying to help ya out.
