Matt,
I wrote Mustang to inquire about the Triumph America/Speedmaster. The reply I got was that they do not and will not have any plans for Triumph cruisers. I have a stock America seat and pillion which I plan on sending to Rick Mayer so he can rebuild it. He's about $140 cheaper than Corbin and everyone raves about his seats.
Personally, I can sit on anything for a short time. The key to avoiding monkey butt, is smooth (seamless, if you can find them) boxers made of cotton,silk or nylon and leather "riding" pants. I don't mean leather jeans. Riding pants, like the V-Pilot pants. Some equestrian suppliers have leather inserts in the back side that work well.
On long rides (over 100 miles) avoid blue jeans. I know, that's what I always wore too. Blue jeans have thick seams in all the wrong places and the texture of denim closely matches the pattern of nerve endings around our hind end.
With the leather slacks I wear, I can sit on that saw horse
saddle that Triumph gave us for 3 tanks of gas before I need a break.
