I went through 3 sets of Duros on my KLR and loved them. They handled well on the road for me since I don't push my luck in twisties and bit in well in muddy hill climbs. Rears lasted me about 5,000 miles.
I've got a front on my G/S and I'm waiting for the rear Distanzia to give out before I spoon the Duro rear on. I really don't think it's going to fit with my Ohlin's shock. The Duros are very wide and the Distanzia rubs already. I'll post up some pics when I get 'em ready. Hopefully next week.
