Yes, you can store your motorcycle in a self-storage unit. Many self-storage facilities offer units of various sizes that can accommodate a motorcycle. However, it is important to choose a unit that is large enough to accommodate the size of your motorcycle, and to make sure the unit is secure and protected from the elements. Some storage facilities may also have specific guidelines for storing motorcycles, such as not allowing fuel to be stored in the unit or requiring the motorcycle to be covered. It is important to discuss your storage needs with the facility and follow any guidelines they have in place.
