Ninja 650 2025 vs 990 RC R 2026

If straight-line speed is your priority, the 990 RC R takes the lead. With 60 HP more than the Ninja 650, 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. Riders with a shorter inseam should lean towards the Ninja 650. Its seat height is 55mm lower than the 990 RC R, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the 990rc offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
