The center of gravity of the Honda Dio is designed to be low and stable, achieved through several key design elements. The scooter features an underbone frame that keeps the weight low, with a dry weight of 105 kg, which helps in managing the center of gravity. Additionally, the fuel tank in some models, such as the Canadian Dio, is located inside the floorboard, further lowering the center of gravity and enhancing stability. This design philosophy ensures comfortable and confident maneuverability, even in tight spaces, by maintaining a balanced and stable ride.
