If straight-line speed is your priority, the Ninja 500 takes the lead. With 3 HP more than the R3, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 2kg 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 ninja500 if you prefer its specific styling and ergonomics, or the r3 if you want the alternative brand character.
