yes that does help I'm with you but again those are ether 19 inch wheel or the wrong bolt pattern
The rim diameter has nothing to do with the bolt pattern for the rotors. Trust me, they don't design new rotors for every different rim size they offer. The bolt pattern is measured from the centerline of the wheel to the bolt holes, not from the rim. The only reason I can think of why H-D says they don't fit other wheels is due to the styling, since that center section isn't going to coordinate very well visually with a Chisel wheel. If you don't care about the appearance difference but you doubt they will fit, measure from the axle to the bolt holes on your bike and then find a SESG with the Agitator wheels and measure that wheel. I'll bet they will be the same.
Btw, if you would prefer a chrome center section with a plain (non-polished) friction surface, you could just buy the replacement rotors that came on the SESG with Agitator rims. An added bonus is they cost less than the polished version with the black center section, MSRP of $189 each and can be found on discount sites like Surdyke for less than $160 each.
