What type of fluid do you put in a gearbox of a x1 pocket bike?

For a X1 pocket bike, you typically use a 2-stroke oil mixed with gasoline if it has a 2-stroke engine. If the gearbox requires separate lubrication, a high-quality gearbox oil, such as 80W-90 or a specific motorcycle gear oil, is recommended. Always check the owner's manual for the manufacturer's specifications to ensure proper fluid type and viscosity.
