Ninja 125 2024 vs ZX-4R 2025

If straight-line speed is your priority, the ZX-4R takes the lead. With 62 HP more than the Ninja 125, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Ninja 125 has a clear advantage. Weighing in 40kg less than the ZX-4R, 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 125. Its seat height is 15mm lower than the ZX-4R, 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.
