Well, my first choice was fz6, however Yamaha stopped producing it.
My other criteria were:
1. I wanted new bike
2. I wanted bike with ABS
3. I wanted bike strong enough for 2 passengers
I was pretty afraid from power of fz8, however today I know that it was good decision.
I'm almost 30 years old, and I don't have little racer in me (at least on public roads). I have ~4000km in 3 months and 1 week, and most of the time I was using up to 6000rpm. Of course I'm slowly adding revs, however I still have a respect. I was on a small circuit once - I tried there how is it when one adds to much power on corner exit, or downshifts with wrong speed/rpms. I was practicing emergency braking, turning etc on parking lot several times. I have read few books about riding...
In other words, as of today I didn't experienced any critical situation caused by inappropriate power usage and I'm trying train deliberately to avoid it.
So yes it's not best bike for novice, but I know it and trying to behave accordingly.
