Abstract
Impact tests and barrier collision tests were conducted to assess motorcycle crashworthiness, protection provided by helmets and other clothing, and the effectiveness of motorcycle air bag restraint systems. It is concluded that crashworthy fuel tanks to prevent rapture; more protection for the head, neck and chest of ejected motorcyclists; and energy absorbing crash bars are needed. Air bags fitted to motorcycles can protect the rider's head and torsi against side impacts with vehicles and prevent ejection in head on impact.
