Hmmm ... surprised to see criticism of the D606 recently. I now have over 2K miles on mine and they seem fine street and dirt, though I haven't ridden in rain (or mud). I finally did a "real" dual-sport ride last weekend, about 700 miles total with maybe 100 off pavement, a few of which were some pretty rocky and loose (by my noob standards) OHV trails in the Sierras, and on a few hills I needed all the traction I could get. But the 200+ miles of slab to-and-from the mountains was handled fine too. And on a few sections of twisty/bumpy paved FS roads (Frazier Creek Rd, Plumas NF - just ride it!) I didn't have much in the way of chicken strips left. BTW, this was the second longish ride I've done since installing ProCycle's lowered pegs and they definitely make a huge difference. The stock seat was really tolerable, and standing off road, though something I still don't feel totally comfortable with, was much easier.
