A motorcycle crash guard assembly, also known as a crash bar, engine guard, or highway bar, is a protective component installed on motorcycles to minimize damage in the event of a crash or tip-over. It is typically a metal framework that is mounted to the motorcycle's frame and extends outward to provide additional protection to the engine, bodywork, and other vulnerable components.

   The primary purpose of a crash guard assembly is to absorb and distribute impact forces during a crash or when the motorcycle tips over. It helps protect critical components such as the engine, exhaust system, and bodywork from direct contact with the ground or other objects, reducing the risk of expensive damage and facilitating easier repairs.
