A sissy bar is a backrest that is fitted behind the driver's seat and provides the front passenger with additional support and comfort. It usually consists of a vertical bar with a padded backrest cushion.
These are often used on cruisers and touring motorbikes and are designed to give the passenger a more upright and comfortable riding position. They also provide a degree of back support and help to reduce strain during longer journeys.
Sissybars are available in different designs and heights to suit the individual needs and preferences of the rider and passenger. They can also be combined with additional accessories such as luggage racks or panniers to create extra storage space. The installation of a sissy bar usually requires appropriate mounting on the frame or luggage rack of the motorbike.
