Ultra - says it all. - nowadays heated seats/grips/gps/cb/upgraded radio
The SEEG is fantastic, but does not have the ultra extras
The RoadKing is fantastic, but is stripped down even more.
If money was no object, and the size of the bike was no object, I'd think the ultra is where you'd want to start.
I can't ride an ultra - does not fit me. I have both a Road King and a SEEG -- both fantastic riding bikes. I like the fairing (upper and lower) more than without, the radio and the display of the gauges more on the SEEG. When it is hot, the Road King can be stripped down to no windshield and it is a way cool - looking and feeling.
Just my thoughts on the subject.
