A few months ago I bought Pirelli Night Dragons for the Harley Davidson Ultra Limited. We have run these tires all summer, just over 5000 miles. They have been run through the mountains (including the Tail of the Dragon), in the rain and the hot concreate of the interstate highways in mid-summer. So how did they fair to date?
Very nicely, is how they performed! In the mountains I could feel the grip as we rolled though the twisties. On the rainy days I never felt that we had any slippage and the high temps never seem a problem either. In comparison to the Harley Davison OEM tires I can already state I prefer the Pirelli’s. That preference is not due to the grip in the mountains but due to their performance in the wet. I truly felt more in control in wet conditions with the Night Dragon’s v. the OEM tires.
So far, tire wear seems to be on par with the OEM, but with only about 5000 miles on the tires it is a bit early to tell. At about 10,000 miles I will have a better handle on this particular issue.
Soooooo, I cannot give these tires a grade yet and most likely won’t until it is time to replace them. But, I can say if you are not comfortable with the wet weather performance of the OEM tire you can truly consider the Night Dragons.
I JUST WANT 2 RIDE!! 
I’ll definitely keep these in mind for my next set. Thanks for the review. I’m in AZ where it’s not necessarily wet that much, but definitely hot!
