If you do not have or want to fit them to OEM 32mm (1.25") Crash dresser bars any that fit the 1" (25mm) foot peg bar will work fine. Goldwing, Harley listings whatever.
A lot cheaper to go Chinese as no doubt Kuryarkins are made their too.
Black Dually and other copies are available cheap with the extended or short arms etc.

I have bought heaps from this seller but they do not ship to the USA but the same items can be found on US eBay or Amazon if you search with the same or similar terms and shows other bike fitment that will suit as long as they are 1" for our foot rails or 1.25" for our OEM crash bars..
