Ninja 400 2025 vs Ninja 500 2025

In terms of raw performance, these two are evenly matched. The Ninja 400 and Ninja 500 produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. Both bikes share a similar footprint on the scale, with only a negligible 3kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Bottom Line: It's a close call. Choose the ninja-400 if you prefer its specific styling and ergonomics, or the ninja500 if you want the alternative brand character.
