Annual numbers of fatal motorcycle crashes have decreased by about 40% from 2005-2009 to 2010-2014 in Norway. An analysis of reports from 249 in-depth studies of fatal motorcycle crashes indicates the following possible explanations: increased rider age, increased helmet use, reduced drunk riding. Other factors are relatively unchanged over timed. Loss of control was a contributing factor in about half of all crashes. Over half of all crashes were collisions with other motor vehicles. Among collisions, 44% were triggered by the motorcyclist, 42% by the other part and in 14% of collisions both parts had been contributing. Road related factors contributed to about 25% of crashes.
