I came off a Yamaha FZ1 to a 2012 Roadster. You will surprised at how well the rocket will handle the curves. I considered keeping my fz1 for the same reason but in the end sold it to make the purchase happens sooner. Glad I did and 1000 miles later the smile is still on my face every time I twist the throttle.
Loved the fz1 but it's "only" a 1,000cc... such a small bike - HAHA
