I was going to get a liter bike but decided AMERICANA was something I wanted so I opted for the buell.... though it doesnt take off exactly like an R1 it still pulls hard, the way i look at it is that with the buell or a 6oo you half to learn how to ride it hard and you must be meticulous about gearing and how you take corners... over all I was right on his ass the whole way and i pushed him through the corners. also the difference on the straightaways was noticeable but i caught up no problem... over all im happy with my choice.
