1. A motorcycle anti-theft device, for a motorcycle comprising a pivotable kickstand, a chassis and an electrical power source, said device comprising: a mechanism configured to lock said kickstand after being set to a lowered position; andan actuator unit comprising an electromechanical device connected to said power source configured to directly drive, when activated, an element to unlock said kickstand,wherein the kickstand locking mechanism comprises a bracket connected to the kickstand and formed with an aperture, and the actuator unit comprises an electrically displaceable pin which is biased to normally protrude from a wall of an actuator housing, said pin being receivable in the aperture of said bracket to lock the kickstand when said kickstand is set to the lowered position and being subsequently driven by the electromechanical device to unlock the kickstand following transmission of an initiating signal to the actuator unit. 2. The anti-theft device according to claim 1, further comprising an immobilizing device mounted in the actuator housing for fixating the pin after having been engaged with the bracket. 3. The anti-theft device according to claim 2, further comprising a controller for commanding operation of one or more of the immobilizing device and the electromechanical device in response to the transmission of the initiating signal. 4. The anti-theft device according to claim 3, further comprising an antenna for receiving an externally originated initiating signal generated by a remote control device, and circuitry interfacing between said antenna and the controller, for transmitting the initiating signal to the controller. 5. The anti-theft device according to claim 4, wherein the initiating signal is a radio wave signal or an infrared signal. 6. The anti-theft device according to claim 3, wherein the pin is configured with a distal flange and comprises a ferromagnetic material. 7. The anti-theft device according to claim 6, wherein the immobilizing device is an electromagnetic device which is secured to a stationary surface of the actuator housing and is in abuttable relation with the flange, a magnetic field being induced for effecting electromagnetic engagement with the pin when said electromagnetic device is energized. 8. The anti-theft device according to claim 7, wherein the electromechanical device comprises a linear solenoid in driving engagement with the flange, a plunger of said linear solenoid being extendable, following de-energization of the electromagnetic device, by a sufficient stroke to apply a force to the flange and to cause the pin to become disengaged from the bracket. 9. The anti-theft device according to claim 7, wherein the actuator unit further comprises a sensor in data communication with the controller, for generating the initiating signal, in response to engagement of the pin and bracket. 10. The anti-theft device according to claim 9, wherein the sensor is an ultrasonic sensor for generating ultrasonic waves that are directed to the flange and for receiving the waves that are reflected from the flange in order to determine an instantaneous distance between a wall of the actuator housing wall and the flange, the initiating signal being transmittable from said ultrasonic sensor to the controller when said instantaneous distance has increased more than a predetermined value. 11. The anti-theft device according to claim 10, wherein the electromagnetic device is energizable at a predetermined time following transmission of the initiating signal. 12. The anti-theft device according to claim 2, wherein the immobilizing device is a mechanical lock connectable with the pin and mounted in the actuator housing. 13. The anti-theft device according to claim 1, wherein the actuator housing is fixedly attached to a portion of the chassis portion and is made of an impenetrable metallic casing. 14. A motorcycle anti-theft device, for a motorcycle comprising a pivotable kickstand, a chassis and an electrical power source, said device comprising: a mechanism configured to lock said kickstand after being set to a lowered position; andan actuator unit comprising an electromechanical device connected to said power source configured to directly drive, when activated, an element to unlock said kickstand,wherein the kickstand locking mechanism comprises: a) a chassis engaging mechanism including a chassis engaging bracket, for fixing one end of the device to the chassis; b) a kickstand engaging mechanism, including a kickstand engaging bracket, for attaching the other end of the device to the kickstand; c) a locking band, one end thereof attached to said kickstand engaging bracket, and the other end of said band comprising at least one opening disposed lengthwise along said band; and d) a lock buckle associated with said chassis engaging mechanism comprising the actuator unit. 15. The anti-theft device according to claim 14, wherein the actuator unit is operable to reversibly lock the locking band by a one-way locking engagability with the at least one opening of the locking band. 16. The anti-theft device according to claim 14, wherein the at least one opening is a plurality of openings. 17. The anti-theft device according to claim 14, wherein the lock buckle is operably attached to the chassis engaging bracket by a lock buckle holder. 18. The anti-theft device according to claim 14, wherein the lock buckle comprises a lever with a tooth adapted to ratchedly enter the at least one opening. 19. The anti-theft device according to claim 14, wherein the lock buckle is housed with a lock-buckle housing.
