Personally, I think all of the new sport bikes are not suited for a passenger unless their butt is about 8" x 8" in size, and their legs are 2 feet long. The pegs are too high and the seat is too small. Only a contortionist would want to be in that position for any length of time, especially on the rear of a motorcycle that accelerates and vibrates like the Z. Try it, go to the dealer and sit back there, just a few minutes will tell you, now imagine it while moving down the road and trying to hang on.
