BMW 310GS Upper Crash Guard

Motorcycle crash guards vary in design, depending on the motorcycle involved and their full purpose.
In general, they provide a metal bar that sticks out past the motorcycle, which helps prevent it from falling completely over in an accident.
Motorcycle crash guards may not reduce your overall risk of an accident, but they can decrease the severity of the injuries that you may sustain in a serious accident.
Crash bars, also known as freeway bars, engine guards, or highway bars, offer some degree of protection to riders in an accident.
