In terms of raw performance, these two are evenly matched. The RS 457 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 4kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Riders with a shorter inseam should lean towards the Ninja 500. 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 ninja500 if you want the alternative brand character.
