As an ex FZ1 owner myself, I think you'll find the bikes somewhat similar in terms of power, handling and weight, it's just that the busa has quite a bit more of what you felt in the Fizzer, know what I'm saying?
After I did an Ivan's jet kit and Yosh pipe, my FZ made 130 hp at the tire which is, of course, some 25 less than a stock busa, but it was no slouch and the power delivery was very linear without any steps or bumps in the way it came on.
Because the busa isn't a peaky machine, it's easy to ride even if you're really getting after it. Just like the FZ1.
The other thing you'll notice between the two bikes is, where the Yamaha begins to sign off at around 140 or so, the Suzook is still pulling like it's in 2nd gear.
Just wait, you're going to love it. The Hayabusa is the most fun I've ever had on two wheels, and that's saying alot because it's the 12th bike I've owned since '89.
