If straight-line speed is your priority, the Ninja ZX-25R SE takes the lead. With 3 HP more than the RC390, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the RC390 has a clear advantage. Weighing in 12kg less than the Ninja ZX-25R SE, 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 ZX-25R SE. Its seat height is 39mm lower than the RC390, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the zx25r if you prefer its specific styling and ergonomics, or the rc390 if you want the alternative brand character.
