Energy attenuation performance of impact protection for motorcyclists

Energy attenuation provided by motorcycle impact protectors (IPs) is a mechanism that can be used to reduce loads transferred to the body of motorcyclists. Impact protectors have been shown to reduce the overall injury risk in motorcycle crashes [1] and severity of fracture injuries in laboratory tests [2‐3]. However, previous research shows little evidence that commonly used motorcycle IPs are effective in reducing the risk of fractures in real‐world crashes. Motorcycle IPs usually comply with the European Standard EN1621‐1, which sets minimum energy attenuation requirements. This study aims to examine the effectiveness of IPs worn by Australian riders in crashes, in terms of EN1621‐1 energy attenuation requirements and injury outcomes.
