MotoGP riders do not turn their handles while racing because it would be inefficient and potentially dangerous. When a rider turns the handle, it turns the front wheel, and can cause the bike to lose traction, slowing the rider down. Additionally, turning the handle increases the risk of the rider losing control, crashing, or losing the race. As a result, riders must rely on body positioning in order to control the bike and maintain optimum speed. By leaning the body, riders can make the bike turn, creating a smoother overall ride and allowing them to remain in the race.
