Make sure realizes that her sitting position on a Daytona 955i is much more agressive than the 500 she is use to. You should go by a dealer and have her sit on one or sit and ride the bike in question. It is also a heavier bike than what she is accustomed to. Also you will need to lower it due to her height. Here's a link for specs:

You may want to consider an older Daytona 600 or 650. Lighter bike to handle... closer to the feel of a 500.
