My 04 883custom is not very comfortable, but it's not terrible. I did a little over 200 miles yesterday after work. Took a grad school final exam and still wasn't totally beat up. It does have an awful suspension. The seat is ok, though.
Right now I'm trying to figure out if I like it with or without the windshield. I love the nice clean air.
I hate the forward controls. Hate. Them.
I love the sound. Love the 53 mpg. Love the little kids always saying 'nice bike'. Love the feel of the bike overall. But the comfort isn't there. When I want comfort I drive a car though. That's easy.
