I had an Ultimate on my VStar 1100 and sent it back. Good quality product, but not for me. It like I was sitting on a playground swing perpendicularly. You sink down and down and down and it crushed my reproductive organs and locked me into place. With the backrest, add in getting bolted upright with all of these other things. It was actually painful.

However, I am the rare one who didn't like the Ultimate on the VStar. Most love it over on that forum.

Best seat - Indian Chieftain, followed by the F6B stock seat.
