If your in a low riding posistion and then you sit up, the center of gravity changes. Is that change possible to make you crash? High speeds? Even if you stand up? A friend who has never ridden a motobike ( andwho exagerates so much that i dont beleive anything he says anymore) was telling me i shoudn't use my body as wind resistence to slow down cause i will crash and die. My body + engine + normal brakes = win?
