If you've ever wanted to replace your OEM footpegs (rider), now might be a good time. I found the part numbers I needed on Kuryakyn's website and did a search online. The tapered adapters needed for the rider's pegs to install any of the Iso-pegs are part # 7946 (comes as a pack of two). On Kuryakyn's website, they are $27.99. Currently on Amazon as an "add-on item" for $5.60 (means that they won't ship them by themselves at that price, but will include them with a qualifying order). I received them today, and they are genuine Kuryakyn parts, and they fit the mounts perfectly.
Thanks for sharing, I needed something that cost $19.75 so I added them to get that price and free shipping. Don't need them right now but may in the future and at that price, great deal.
Thanks Again
