Handling is the first thing that hits you in the face when going from the NSR to the RZ. The Honda will walk on the Yami pretty easily. The guys I ride with have modified RZ's that make good power so on the straights maybe 40-70 mph it's pretty even. After that I'm gone. Braking no contest not even close. In the tight 1st gear stuff the RZ feels easier to throw around weight wise. Seating position the NSR is a sport bike the RZ is more of a standard type deal.
