He said that he had a 250 for over 5 years. The Hayabusa has a longer wheelbase, additional weight, more torque, and better ergonomics; I think these properties make it more stable and easier to ride on the street than a literbike. The power to weight ratio of modern literbikes is higher than the Hayabusa. I've never ridden a Hayabusa, but I have sat on one so I might be wrong.
