If straight-line speed is your priority, the Monster takes the lead. With 16 HP more than the Tuono 660 Factory, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Tuono 660 Factory 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: While both are capable, the monster offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
