What is a sissy bar?

A sissy bar is a vertical metal support that is attached to the rear of a motorcycle's seat. Its primary function is to provide additional support to the passenger, especially during high-speed maneuvers or sudden stops. Sissy bars come in different heights and styles, with some featuring a pad for additional comfort. They can also be used as an attachment point for luggage or other accessories. Sissy bars are commonly found on cruiser-style motorcycles and are often highly customized to match the rider's preferences.
