I've never really been a fan of Harley seats. It's not that they're badly made, they just never seem to fit me that well. I've also never much cared for the huge-hunk-of-foam out back. So when I got a new M8 a couple years back I went from this: to this, a Mustang Day Tripper: 'nice seat, low profile & lets you move about a bit. I took it out west a few times and it was fine. Still, it always seemed to want me sit an inch or two more forward than I really wanted (6'2"). Mustang has one (Super Tripper) that moves it back but it doesn't offer a back rest & since for me this is primarily a touring bike I wanted to give that a try too. I found it in a Le Para Outcast Daddy Long Legs. Outcast because it has a minimal passenger section (that lines up perfectly with the detachable rack I use to form an ideal platform for my seat bag). Daddy Long Legs because it moves you back an inch or so. The back rest is nice, easily adjusted or taken on and off (w/o tools). I haven't used it much but on the next big trip I plan to: It's a VERY well made seat by the way, the pan alone is about as stout as I've seen in years. Anyway, as this is a new one to me, in case you are looking for more room in a one piece that will line up with your rack & comes with a detachable, adjustable backrest this is a good option at roughly $650.
