evidence: Older motorcycle riders are up to three times as likely to be seriously injured in a crash as young adults, according to new research from Brown University in the US. [...] While the study did not indicate the types of motorcycles involved in crashes or circumstances surrounding the crashes, the authors of the study said that previous research suggests older adults are more likely to purchase motorcycles with large engines than young adults are. [...] "As well as the need to think about additional strategies to decrease fatal instances in older motorists, we could also look at improving roads, riding conditions and road behaviour."
