I need a bike that is suitable for my wife to ride, she likes the ZX6R but it has to much of that lean forward feel for her and she would like to have a bike that has a more upright seating position. would like something with enough go but not to much, am I making sense

Has anyone had a ride on either or both of these bikes? how do they compare power wise? is the 750 more revvy?
Very interested to hear peoples opinions,
Thanks
