Had an 04 SV (naked) and traded it in 08 for a new DL650. A little performance difference. The SV pulled harder up high, and longer, but with a little more mid range on the DL, you never really missed it. It was strictly an issue of comfort for me. The SV had all the performance I wanted, but not enough leg room for my bad knees, and seat that was among the worst I had ever put my ass on. The DL does have less covering clearance, but there's more of it than you think. And the huge fuel tank is just awesome. And it's like a pack mule. There's no end to how much crap you can load on it, and just keeps chugging along.
With the right tires, the SV was surprisingly good on dirt roads, and a bit of a weapon on pavement.
If I were offered the choice, I'd likely take the DL.
If you get far enough away, you'll be on your way home.
Piss off, I'm in my Happy place.
