I do not have any of those Honda bikes & have Honda 929 & 954.
Still I am pretty sure there are some pretty dramatic changes between the CBR 600F4I, and the CBR 600RR. Best to find a road test on both or at least the 600RR & they will mention said changes.
Like most feel there are no changes on the 929 & 954 other then cc of engine size only far, far more like better torque at lower revs, larger rad, rider is moved several inches farther to the front, clip-ons down a bit lower, better stopping power, that one fits better into the petrol tank, that it corners better & such.
Though most will not even feel this for they are NOT experienced enough riders to FEEL the difference.
