Technical safety measures call for detailed knowledge of how accidents occur. Accidents involving two-wheel vehicles pose particular problems in describing the course of the accident and injury severity as well as ascertaining the causes.
Using material covering approximately 3,500 accidents with motorized two-wheelers, a realistic classification system is explained and problems of the different two-wheel categories are shown in this paper.
Experimental and mathematical simulations of the main accident type lead to some suggestions on how to change the motorcycle by adding some safety elements to reduce the injury risk of the driver.
A safety motorcycle is introduced that can improve, in a positive way, the flight path of the driver after an impact without being unrealistic.
