The difference between your bike and a Nighthawk is a function of many things. Mostly technology, but the entire state of tune of both engines is totally different. Basic design, cam grind, comp. ratios, fuel system design and tune, exhaust design.... all that gives any engine it's characteristics(read: personality)...
You can't really tell how an engine 'feels' by looking at numbers, unless you have a boatload of numbers for that engine, and know what they mean. And then taking the rest of the chassis data into consideration, and factoring all that together..... it's easier to just ride everything you can beg, borrow or steal. More fun too.
But you have to study each bike carefully so you can catalog what you feel with what you see, divide that by what you know, cross-reference it with other equipment you rode in the past, multiply all that by what you've forgotten, and file it away someplace in your head that still functions reasonably well so you can retrieve it later. Then you can make broad, sweeping general statements like me....
