In terms of raw performance, these two are evenly matched. The 450SRS and Ninja 400 produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. When it comes to agility, the Ninja 400 has a clear advantage. Weighing in 11kg less than the 450SRS, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: It's a close call. Choose the 450srs if you prefer its specific styling and ergonomics, or the ninja400 if you want the alternative brand character.
