The bottom line here is "How do these pegs attach to the bike"? As others have stated, Ness makes pegs for both Harley's and Victory's and they may well be different measurements. However, as others have pointed out, you can buy the correct components to connect these to a specific bike.
I have subscribed to this thread because I am in the middle of putting some highway pegs on a Cross Country and was interested in what others are doing. In my case, I have some Kuryakyn Short Magnum footpeg "adapters" (made for Harley) that will be here tomorrow. I also have some Ness footpegs (made for Victory) that will be here later in the week. At that time, I will be able to tell you if my solution will work so that may give you some guidance (if your considering using adapters).
It's not just any victory.... It's MY Victory!
