If straight-line speed is your priority, the ZX-4RR takes the lead. With 5 HP more than the YZF-R7, 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 0kg 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 31mm lower than the YZF-R7, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the zx4r if you prefer its specific styling and ergonomics, or the r7 if you want the alternative brand character.
