That Suzuki is a GREAT bike. I spent a lot of time atop that bike during the demo days (state8 & IMS show), when i was working for Suzuki. Very good power. They basically used the same forks and brakes from the older gixxer, and the engine also. Suzuki seams to have finally sorted there transmissions also. That 1000 seemed to shift very smoothly for me on both occasions AND it had neural lock out (about time Suzuki).
Its a very nice, "cool to ride" bike. In the mornings i would hop on the gsxr's because it was cool out, Then in the afternoon i was on either the gsx1000f or the sv650 and was nearly 98° that one afternoon. And it was tolerable. I was laughing at the suckers setting on those sport bikes in the middle of Columbus traffic in that heat.
I rode the z900 & GSX1000F back to back down at Columbus last summer and would have to say its a really tough call. I like how light the clutch is on the z900 and the whole bike is crazy light weight, but i would want the fairings. Perilously, im dragging my feet on a new bike, and hoping maybe Kawi retires the old Ninja 1000, and replaces it with a new Ninja 900 built around that platform. But if i was buying today, I would for sure get that suzuki.
