In terms of raw performance, these two are evenly matched. The Monster and 890 Duke GP 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 890 Duke GP has a clear advantage. Weighing in 5kg less than the Monster, 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 monster if you prefer its specific styling and ergonomics, or the 890duke if you want the alternative brand character.
