International Standard 13232 provides common research methods for assessing the feasibility of proposed protective devices which might be fitted to motorcycles. This paper reviews the Part 7 computer simulation requirements of the Standard; and applies the simulation to an example injury risk/benefit analysis (Part 5) of a proposed UKDS motorcycle leg protector device. Overall, the computer simulation and injury risk/benefit analysis portions of the Standard were found to be practical and feasible. The analysis of the UKDS leg protector indicated that a motorcycle equipped with this device increases total injury costs to motorcycle riders in impacts with passenger cars, and therefore should not be fitted to motorcycles.
