Not sure you will like it mate but she has got her heart set on a the new Kawasaki Ninja Z500 A2. One of my curmudgeon crew has one and she fell in love with it. .
Mainly because it is small and light (164 kg) and they do a red and black one.
I think a Honda CBR500R would be a better option for her but I do have a Honda thing, plus Dads know nothing.
