I installed the Pirelli Dragons on my 13 CVO Ultra about 3 weeks ago I've got about 1200 miles on the so far. I was torn between the Michelin Commander II, the Continental Milestone Mileage Plus and ended up with the dragons. Ive had the Michelins before and they lasted me about 1200o Miles with still a bit of tread left but severe cupping both front and rear, not sure why as I check tire P religiously .
But back to the Pirellis. Had my indie mount them and then realized he didn't balance them. I took the from off and Balanced it and as I was headed out to the rally the next day I searched for some type of balancing bead and added "Counteract" beads to the rear. They handle "great", they do tame the tar snakes and unevenness's in the road, they're very sticky (after about 100 miles of breakin) and i was wondering how they would do in the rain, well it poured on us a couple of days and the were excellent in the rain and really cut through the deep standing water well. I'm still concerned with the balance and would suggest that you make sure that they index the wheel and balance the tires well when you install them if you go that way. So, so far I'm happy with them, time will tell from a wear standpoint though. Oh I ride 2 up a lot w/andW/O packed bags.
Good luck
