If straight-line speed is your priority, the Ninja 400 takes the lead. With 30 HP more than the R125, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the R125 has a clear advantage. Weighing in 24kg less than the Ninja 400, 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 35mm lower than the R125, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the ninja400 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
