When it comes to sport bikes, or today's naked sports machines like the Super Duke, you have to make your decision based on the engine. There is no use comparing specs...every modern liter bike will be far more than you can handle or is needed on public roads. In fact, even on under 2 mile courses for track days, liter bikes are overkill and rarely get out of 2nd gear. (I have a Daytona 675R for such endeavors and it's perfect.)
The character of the engine...V-twin, Triple, I-4, Cross-plane I-4, V4...is so important to the experience and preferences of the rider in this class of machines, that all of the other aspects pale. If you're not a V-Twin fan, you'll hate the Duke, no matter what. If you love silky I-4's then the CB1000RR SP could be just the ticket. But you're not likely to love both. So, think about that, determine what floats your boat, test as many as possible, and buy the one that makes you all tingly inside.
