Got to admit that the R1 is a bit more responsive than the fz, in both cornering and acceleration, but it'd be a close one in a drag race between my old bike and the new one!
I could corner the fz like a demon, but as you said, your sat upright. I wore out the edges of my last rear tyre, but it always felt stable, and never skittish like my R1, but then again, the forks are a bit buggered!
In some ways I miss the fz, and in other ways glad I've got the R1.
