RS 457 2026 vs Ninja 400 2023

If straight-line speed is your priority, the RS 457 takes the lead. With 3 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 7kg less than the RS 457, 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 RS 457, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the rs457 if you prefer its specific styling and ergonomics, or the ninja400 if you want the alternative brand character.
