Welcome.
My stock seat on my '05 S83 never broke in, especially hard on the passenger. Finally replaced it at 18000 miles with a Mustang Wide Regal. Now my wife is happy, it is much more comfortable for her. I'm not so happy. The seat has moved me forward about an inch, so there is less upper thigh support, and I feel cramped on it. However I can ride 2 to 3 times farther before my backside starts complaining, and it looks a lot better than the stock seat.
As for the rest of the bike, I love it. Routine maintenance is a snap. Two things I have learned from other members on this group to watch for is loose battery terminal connections - check them a couple of times a year, and rear brake pads - the inside pad wears quickly - keep an eye on it. These pads are extremely easy to check and/or replace. By far the easiest I've ever seen.
