The use of motorcycle and their accident rate has grown significantly in Iran in recent years. Due to the higher vulnerability of motorcycle riders the numbers of injuries in motorcycle accidents are higher than other vehicles (about 54%).

The most vulnerable part of body in motorcycle accidents is the leg;​ as in about 60 percent of motorcycle accident that cause injuries, leg injuries are perceivable. One of the accessories which can be helpful in reducing leg injury, are the motorcycle leg protectors, especially the front leg protectors. In this paper, collects data and information about the accidents that cause injuries and the number of injured motorcycles which are equipped with leg protectors and of those which are not, and also the rate of using the leg protectors in the community of normal motorcycle riders and those who have had injury accidents, is analyzed. The data has been gathered from available accident data, vehicle counts, and interview with motorcycle riders. For the purpose of statistical analysis of the data, graphical analysis and statistical tests, i.e. the likelihood-ratio test in two communities, and K-test, has been used. Additionally, Chi2 test has been applied for analyzing the results and examining the validity of the data.

Finally, it has been concluded that according to the existing statistics, it can not be inferred that installing the front leg protectors significantly reduces the rate of injury accidents. However, observations and surveys reveal that these protectors have a positive impact on reducing the leg injuries in non-severe motorcycle injury accidents.
