FWIW - I test rode the Suzuki 650 and 650s before buying my FZ6. I found the seating position/ergos on the Yamaha better than all the other bikes (especially the "s" versions of the Suzuki due to the clip-ons and slightly farther back rear-set). The FZ6 also has great power available - now that I'm past my initial 600 miles check/tune I can open it up a bit more and this bike easily breaks ALL speed limits without leaving 3rd gear!! I also love the look of the undertail exhaust and the digital gauge. Lastly, the FZ6 comes with a centerstand (not an option for the Suzuki's per my local stealer/dealer).
Obviously I'm biased, but I really love this bike.
