Ninja 400 2023 vs ZX-4RR 2025

If straight-line speed is your priority, the ZX-4RR takes the lead. With 32 HP more than the Ninja 400, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Ninja 400 has a clear advantage. Weighing in 21kg less than the ZX-4RR, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Riders with a shorter inseam should lean towards the Ninja 400. Its seat height is 15mm lower than the ZX-4RR, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the zx4r offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
