RS 660 2022 vs YZF-R9 2026

If straight-line speed is your priority, the YZF-R9 takes the lead. With 17 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 12kg less than the YZF-R9, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: It's a close call. Choose the rs660 if you prefer its specific styling and ergonomics, or the r9 if you want the alternative brand character.
