The reason it doesn't matter in a scooter is fairly simple. A motorcycle is unit construction and shares engine lubing with its gearbox. a motorcycle experiences molecular shear as the oil is compressed in the gears. A scooter has a separate engine and transmission like a car...and a Harley. 10W-40 car oil works in the motor, 85W-90 gear oil in the transmission.
