u didnt even read what i wrote, i actually said exactly the opposite, in MANY motorcycle crashes and accidents the rider lives and doesnt suffer permanent damage to their body except for skin grafts in some cases.
Because of the whole you not staying on the motorcycle and then flying off and the bodys tumbling naturally dissipates alot of the energy off the crash while doing minimal amounts of actual damage to a person however collisions (hitting something like a truck or a deer) or being hit is another story
