A locking device of a motor cycle disk brake has a body provided with a slot perpendicular to one of the sides of the body. A locking bolt is disposed in the body such that the locking bolt can be caused to move between a first position and a second position. When the locking bolt is located at the second position, the locking bolt seals off an end of the slot. A locking apparatus is housed in the body and is composed of a lock core capable of being caused to locate at a third position or at a fourth position at such time when the locking apparatus is in an unlocking state or in a locking state. The lock core is coupled with the locking bolt in such a manner that the axes of the lock core and the locking bolt are parallel to each other. The locking bolt and the lock core can be caused to act synchronously. When the locking bolt is caused to seal off the slot, the locking bolt is simultaneously aligned to pass through one of the heat-radiating holes of the disk brake, thereby incapacitating the motor cycle.
