Motorcyclists are also 40 times more likely to suffer serious injury than car occupants.
Last year 240 motorcycle riders were killed and 5000 admitted to hospital.
The report found many of the fatal accidents occurred on weekends and between the hours of 2pm and 6pm, indicating recreational riding, rather than commuting, was linked to the accidents.
Excessive speed and alcohol were the two biggest causes of fatal motorbike accidents and one in 10 involved a rider not wearing a helmet.
