I use the £99 jobbies off Ebay and make an adapter plate with multiple fixings.
The ones on my 750SSie are ZXR400 rearsets with some fairly simple adapter plates, the spares are carried by some of the paddock trucks like A&R racing and the adapter plates allow for a fair bit of adjustment.
Something like these could be made to fit, I adapted CBR400 ones on Senna3's DD bike
