If straight-line speed is your priority, the R6 GYTR takes the lead. With 41 HP more than the ZX-4RR, 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-4RR. Its seat height is 50mm lower than the R6 GYTR, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the r6 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
