As far as I know there is just one adapter size for the Kuryakyn pegs. Kuryakyn advised the adapters were on backorder until March, I got them through Ma's in a couple days. I recently bought the switchblabes for the front and ISO wings for the back, both Kuryakyn. Very pleased with both the look and function. There are covers for the brake and shift lever. They are clam shell style, I did not get them. The stock covers look okay and I was afraid they would appear too large. Go to
