A service motorcycle, also known as a service bike or motorcycle service unit, is a specialized motorcycle used for various service and maintenance tasks. These motorcycles are commonly employed in urban areas where navigating through traffic and reaching congested or hard-to-access locations is challenging for larger vehicles. Service motorcycles are equipped with storage compartments, toolboxes, and racks to carry tools, equipment, spare parts, and other supplies needed for performing maintenance, repair, or delivery tasks.

They are commonly used by industries such as courier services, postal services, emergency medical services (EMS), law enforcement, and mobile repair services. Service motorcycles offer agility, speed, and flexibility, allowing technicians, couriers, or emergency responders to quickly reach their destinations and provide efficient service. They are often customized to suit specific needs, with modifications such as reinforced suspension, extended fuel tanks, or lighting and communication systems.
