Just wanted to add my comment as a new rider too. I took a motorcycle course here in Montreal two years ago, then only bought the FZ6 now. Was a very good course though with some amazing instructors. I am still on learner at this point, full road test later this year.
I initially was looking for a 500cc, something that I thought I could handle and last me a few years. I've gotten advice such as 'Always get a bike bigger than you think you can handle'. Since I said 500c, I was told to get a 800cc at least. That sounded crazy to me. Unfortunately, I did listen a bit and got something a bit bigger... got the Fz6 2007 two weeks ago.
However I haven't dropped it so far with some 200Km covered. I am 5"8 and 165Lbs and I think I have been able to recover because I can manage the weight of the Fz6. I am glad to hear that the clutch is a challenge for others as well on the Fz6, because I thought it was just me. I haven't ridden other bikes other than the Fz6 and the course's bikes (250cc and 400cc) so I wouldn't know. After too weeks, I still think I need to practice the friction point and be able to get in motion smoothly and at an angle. Such as negotiating a turn at a stop or leaving a parking spot in the city with only a lane to manoeuvre a 100deg turn. Doesn't help either that we have many roads that slope up or down. I do it but it is far from smooth and sometimes I give too much throttle because I am afraid I will choke it. I have been doing it without damage so far but it just feels shaky - too much rev, paddling the road with my feet a couple of times before I am secure. Good thing I have held up the clutch well and not let go! I can think of a few cars that I might have kissed if I've go of the clutch... A few of them super cars (F1 week-end, lots of super cars here). The gas feels over sensitive specially during those starts. I have adjusted my clutch to bring the friction point closer yesterday, that did seem to help. Previously I almost had my hand fully extended before I would reach the friction point. Have to try more.
The few good things that I did at least was to read about the Fz6 before buying and most articles say it is a good bike to start for those who have not ridden for a while, some say it is good for beginner as it does not have lots of torque until further up the rev. Heck I believe them. Also not to hop on the Fz6 as soon as I paid for it. I got a friend to ride it for me to an empty space. Took an hour to get used to the bike. Choked it many many times before I got the friction point ok. Redid my course exercises and practising emergency braking. The first tweak I did on the bike was to go to the garage and ask them to oil the clutch cable because the clutch feels so hard. It did help just a bit, I still think the clutch is too hard. Spent many hours learning about the Fz6 (this forum is great for that) and motorcycling in general. One odd thing I did too was go on youtube and watch others do silly things on their bike and fail so as to remind me of stuff NOT to do. Last but not least, I have not ridden with the people who have advised me to get the bigger bikes; I have kept a couple of saner people around me to accompany me to ride.
So far I think I will be ok with the Fz6, but like someone said, height and strength is possibly a factor at the beginning. On a plus side, I think the gears are super easy. Can find the neutral each and every time
Take it easy, keep working on getting more comfortable with your motorcycle before you hit the road. In case you hit the road and realise that there are things you have to improve. Go back to a safe place and practice. (I am giving myself advices too btw

)
