You do ride faster on sportbikes and yes you would ride differently than on a GS. You can reach the limits of a GS quicker and be just as much of a twat on one but TBH sportbikes - IOW - anything over 100 bhp on the road is useless. Sportbikes are just getting started where the GS finishes and their suspension etc work much better at higher speeds. Many are boring where the GS shines. The Fireblade is a good choice being the most road worthy of sportbikes but it is comparatively useless. Ultimately the wife is looking out for you / kids. Maybe it isn't the bike so much as you. Most women or men I know who have issues with their spouses / SO on bikes is more about how the spouse / SO rides than the bike itself. Maybe she had a friend etc who had a sportbike. Young males are dumb and many a woman I know refuse to get on my sportbike after riding one when younger and some idiot going crazy on it with them on the back. That would leave a lasting negative impression. I've ridden bikes for over 22 yrs and with all the options out there if my SO was accepting of certain models over others I am sure I could find a compromise. Want something sporty but not a sport-bike. Get a KTM Duke or 950SM or the Ducati Hypermotard etc. All the sportbike flavour without the wife pissed off. Plenty of other options out there. Edit: I see you bought a Fazer... exactly my point. Good for you.
