If straight-line speed is your priority, the CBR600RR takes the lead. With 36 HP more than the ZX-4R, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 1kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Riders with a shorter inseam should lean towards the ZX-4R. Its seat height is 23mm lower than the CBR600RR, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the cbr600rr offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
