If straight-line speed is your priority, the Ninja 400 takes the lead. With 16 HP more than the 300SR, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the 300SR has a clear advantage. Weighing in 13kg less than the Ninja 400, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: While both are capable, the ninja-400 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
