Just pulled off a set of Pilot Roads after 6700 mi and put on a set of Pilot Powers. My immediate impression? FANTASTIC!
The Roads were a big improvement over the 90X's that were OEM, and they seemed to wear well. Very good performance in the wet, too. I did notice, however, they were a tad vague when whipping the XX around more agressively. The front wore a bid strangely as well, but nothing as extremely bad as the 90X's. Those were absolute crap after less than 3000 mi.
Now, compared to the Roads, the Powers made the XX immediately more responsive... and they stick like glue. Haven't tried them in the wet yet (doesn't rain much around here), but I've noticed that the handling (new) is better than the Roads (new) were. The feedback from both ends is what I expect, and a welcome relief from the previous tires' feel. Of course, I can't comment about longevity, but after about 900 miles they are wearing pretty much as I expect a softer tire to. To be honest, though, I don't much pay attention to wear rates where good handling is concerned - when they're ready for a change, I change them. I'd rather do more changes with great tires than fewer changes with ones that give me the heeby-jeebies during my rides.
Comments about riding two-up on these tires don't have me concerned, since I rarely do (the mrs is content to ride her 750 Katana). The Roads weren't bad, in case yer curious. I don't expect the Powers to be particularly great for two-up, though, looking at their design purpose and heritage.
I'll keep you up on the Powers should anything significant arise.
Best to you.
