Recently came across this interesting info about motorcycle safety, specifically braking, and the misconceptions about required braking distances. The information originates from a 1981 report, ironically titled the Hurt Study…
In the report, it is stated that rider error was present in approximately 2/3 of single vehicle accidents. Many of these accidents were caused by incorrect braking, and an inability to judge the proper technique needed to safely slow the bike.
As stated on the Motorcycle Safety Info site:
Most riders do not fully understand the distance that is required to bring the bike to a full stop. Braking distance increases with speed, and unfortunately the increase is not linear.
If a bike that is doing 30 MPH can stop in 33 feet doesn’t means that if the same bike is doing 60 MPH would be able to stop in 66 feet, it actually will take 134 feet! The increase in braking distance is the square of the speed increase.*
