I have an '05 S83, the more miles you put on it the seat gets better. I'm just shy of 10,000 miles and it is pretty good for me upto about 350 miles before my butt starts getting numb and tingly. When new about 100 miles was all it took. I noticed it starting to get better after about 3500 miles. I've read several places as well as read posts here saying that it takes 3000+ miles to break a seat in real good.
