Everyone will recommend almost any other bike rather than the DR650s, but they are such underrated little gems. With the minimum of care they will just keep going. Long road tours aren't fun but they are doable, but once you hit the gravel, they excel. They can carry quite a load, so you can go on long tours, but they are still light enough for fun. Many people are doing round the world tours on DR650s, because they are so dependable.
And they are so slender and easy to ride. People at traffic lights sometimes ask whether I'm riding a DR250. Weighing in at 147kg dry, you won't get a lighter nimbler dual sport that won't cost you an arm and a leg to "adventurise". Adjust shocks to your needs, put on some 50/50 or full on knobblies, drench the engine in oil and point it anywhere.
I've surprised myself where I managed to go in/down and back out again with a fully loaded bike (got lost, I'm not into GPSs). I can't imagine riding solo for weeks on any other bike, dropping it and picking it up in the middle of nowhere, barely giving it a glance over, mounting and riding off again

Edit: Friend of mine has had a DR650 from new, I think, and recently it reached the 90,000km mark, no hassles yet.
As you can tell I'm a bit passionate about my DR650s
