In terms of raw performance, these two are evenly matched. The 990 Duke and MT-09 Y-AMT 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 990 Duke has a clear advantage. Weighing in 6kg less than the MT-09 Y-AMT, 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 990duke if you prefer its specific styling and ergonomics, or the mt09 if you want the alternative brand character.
