Have had them on My Buell Cyclone for about 2000 miles and about 6 months. Much better than the Dunlop 205's they replaced. Much stickier, and they turn-in much better. I expect them to last about 5000 miles, which is pretty good, as the much harder 205's lasted about 6000 miles. This is with a 500 lb. bike, 200 lb. rider, and 80+ ft./lbs of torque @ 3000 rpm. On My next go-around, I would either buy the Pirellis or D208's - but not because there is anything wrong with the Pirelli's! Dunlops are just what the Buell Dealer carries in Inventory...
