It handles very well, much better than stock and even far better than my upgraded (.85 springs, 20wt oil, emulators) stock forks.
There will always be bumps that jar you, but its how the front end handles them, what it does to your control of the bike that makes the difference. There's no solution that will completely eliminate you feeling the bumps, nor would you really want that, but I have to say this front end setup really smooths things out reaction wise and that's what is important to me. Small bumps and chatter from rough pavement are dramatically reduced, and the big bumps are dulled down and no longer upset the handling. You still feel them but they aren't nearly as jarring.
As far as cornering, well the geometry has changed so that is taking a little getting used to, but overall I think I like the change. Turn in is quicker (at the loss of a little stability I think) and I can take sweepers at a lot more speed and lean angle than I could before with any confidence. Without the pogo-ing that would make me run wide. In fact the front is
so much better that I'm really starting to feel the deficiencies in the
rear (GSX-R1000 shock back there)... so I guess I need to address that next.

As a side note there's really not much you can do about road comfort issues with sport bikes... the suspension just isn't designed for it. A good quality, well set-up sport suspension (car
or bike) will be stiff and harsh on the road. Its made for the track--not the street--because you want all the feedback from the tires that you can get. That being said this upgrade was a big improvement and I finally have the adjustability now to control the front end for whatever the riding conditions.
