I also came from ZX6R's and in my opinion the ZX10R is actually a lot easier to initiate turns at race/advanced pace. I struggled massively with front end chatter issues on my ZX6R, I went every which way with geometry and although I found a "sweet spot" it was never as good as i wanted it.. I hopped on a friends bike and was immediately amazed at how the bike didn't chatter and how easy it was to actually toss around.
There are some physics stuff that comes in to play as far as gyroscopic effects of the crank and the bike being slightly heavier, but all in all, the Gen 5 ZX10R is a dream to ride compared to my 09-12 ZX6R's.
