Getting back to OP. I wouldnt hesitate to add a riser. Suggesting accomodating is fine especially if youre 6 feet tall or longer arms. but one size does not fit all and the suzuki is a long reach for 5’8” and shorter. I rode bycycle a lot and can do 3 hours cycling and am in good shape - but its a lot more dynamic activity with position changes constantly. On the motorcycle I dont try to talk myself into saying I am comfortable. Imagine a car with non adjustable seat and steering wheels?? .

The Busa has a longer gas tank and longer reach to the bars than a Gsxr or any liter bike.
