RS 660 2026 vs Ninja ZX-6R 2026

If straight-line speed is your priority, the Ninja ZX-6R takes the lead. With 22 HP more than the RS 660, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the RS 660 has a clear advantage. Weighing in 15kg less than the Ninja ZX-6R, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: While both are capable, the zx6r offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
