LOL it's his first bike! The 6R is top heavy compared to what? How is he going to prepare for it?Two things, the FZ6R is very top heavy, prepare for it. Use your core and arms when you move it around. Don't be afraid to man handle it when moving it around etc. Be careful, have fun, and BE SAFE!
Personally, I love the way it handles. It's stable at highway speeds, not difficult to throw it over when I want to, and I like the way it dives into a turn, if you let it.
It's not a Ducati. It's not a Triple. It's not a Gixxer. In order, it doesn't handle as well, doesn't have as much torque and doesn't have the top speed.
It's still a better bike. It's a little bit less than most dedicated sport bikes, in their chosen niches. However it does everything very well, where the others often fall short in a category that they are not meant for.
Touring on a Ducati? Have a chase vehicle. Giving your bike some more gas in a tight corner, because you think you can run it a little faster than you thought? Mid corner? Do that on a Triple.
WOT from a stop sign, with a nice sweeper ahead? Try that one on a Gixxer.
I'm a fanboy of the 6R, and I'm not ashamed of it. It's a freakin' awesome motorcycle. You can ride it hard, and it's still forgiving. You can ride it easy, and it's still comfortable. You can commute on it. You can tour on it. You can dog it and get your jollies on.
Top heavy? That's an opinion I don't share. Once I break vertical, she wants to dive into the turn. I let her do it. I like it.
