While I think a larger bike like a Multistrada V4 would be better for your height (test ride it, its fun!), if I were you size (only 6'1" here), I would get the rocket and pay the money needed to a custom builder to fabricate the aluminum extensions needed to extend maybe a couple inches forward/outward the the forward controls, and to modify the seat area a bit to get another inch or two there... before deciding for the rocket, I was thinking to just get myself a zx14 and modify it for a more comfortable position.
