A seat cover for a motorcycle is a protective and decorative accessory that fits over the motorcycle's seat. It is designed to shield the seat from wear, weather, and dirt, while also enhancing its appearance. Seat covers are typically made from durable materials such as vinyl, leather, or fabric, and may be padded or have additional features like water resistance or custom designs. They help maintain the seat’s condition, provide added comfort, and can be easily removed or replaced for cleaning or style changes.
