Ratimick, i took all three bikes for a test ride today and i have to say, the Z750 was the pick of the bunch by far.
Im a bit short and i thought i might have problems stopping at lights and such but i just had to make do with flatfooting my left foot and keeping my right on the pegs.
The Z was smooth and had fuckin heaps of power, it was so awesome. My only complaint was that in first gear at about 6k revs it was a bit viby, im not sure why but hopefully mine wont be like that .
The Sv650 was also very nice, very smooth, and very nice to ride, but it didnt have the excitement that the Z gave me. They were trying to get rid of their '04 stock as well and they were only $10,250 ride away.
Lastly the FZ6. I really didnt like this bike, it was really jerky from takeoff. It was almost like learning to drive again and bunnyhopping away from the lights at one point. The gearbox wasnt as smooth as either the Z of the SV.
Im still in negotiations at the moment as my loan hasnt been approved yet, but im definately going to be getting the Z
