In terms of raw performance, these two are evenly matched. The Tuono 660 Factory and 790 Duke produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. When it comes to agility, the Tuono 660 Factory has a clear advantage. Weighing in 6kg less than the 790 Duke, 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 790duke if you want the alternative brand character.
