If straight-line speed is your priority, the GSX-S750 takes the lead. With 17 HP more than the Tuono 660, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Tuono 660 has a clear advantage. Weighing in 30kg less than the GSX-S750, 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 tuono660 if you prefer its specific styling and ergonomics, or the gsxs750 if you want the alternative brand character.
