The system is composed of an assembly mounted on the steering pivot by means of a plunger (27). By pulling on the lever (37), the security disc (36) is moved rearward and releases two screws (34) which allows the disc (12) to rise by rotation pressure. The disc with the handlebar released makes a quarter turn and comes into the locking position. Then the security disc returned by a return screw fitted with a spring returns to the initial locking position. |
