I also want to know all that. I believe the buckhorn bars or pullbacks you mention are the older style and the new ones are better called something else like drag bars, flat bars, etc. That's just my opinion....Dan
I think you're correct.
The newer S40 has taller risers and if you install the bars off of a ls650 the cables and lines might be too short unless you change the risers also.
