Harley-Davidson motorcycles typically do not have a specific feature to turn off the mirrors. However, if you want to temporarily disable the mirrors for some reason, you can fold them inwards towards the handlebars. The mirrors on Harley-Davidson motorcycles are usually mounted on a swivel joint that allows them to be adjusted. By gently pushing or pulling the mirrors towards the handlebars, you can fold them inwards, reducing their visibility and preventing them from sticking out. To restore the mirrors to their original position, simply pull them back outwards until they lock into place. Remember to adjust the mirrors properly before riding for optimal visibility and safety.
