748's a nice bike, but as has been said if I was going to get one I would go for 916. Same bike more poke. You have to remember a stockish 916 will only just break 100hp, a 748 doesnt have that much power or torque.
However it has a fair bit more bottom/middle than an NSR. Depends what your after really, they are chalk and cheese.
You have to wind a 748 up like an NSR in some ways to get it to go. If you have to wind something up though I guess you might as well wind an NSR lol.
