Very interesting study.

"The one percent
Riding a motorbike can be dangerous. Our data shows a total of 7,004 bikers and their pillions lost their lives between 1999 and 2010.
Motorbikes account for just 1% of road traffic, but over a fifth of all fatalities, a casualty rate that is 61 times greater than that for cars.
Our research suggests the riskiest time for bikers and their pillions is the weekend when fatalities are considerably higher than during the week.
The pattern during week days is very similar, showing peaks in the morning and afternoon rush hours.
On the weekend however the number of people dying is much higher, particularly on Sunday afternoons."
