US Patent 7281400 Padlock for motorcycle brake disk

A padlock for motorcycle brake disks having a body with a neck whose width is adjusted to the thickness of a motorcycle brake disk, and a latch which can pass through one of the conventional orifices of this brake disk. The latch operates between a retracted position within the body and an extended position in which it penetrates with its tip into a locking mechanism formed inside the body itself. Once the padlock has been positioned on the disk brake, the body prevents turning of the wheel because it abuts against the motorcycle chassis.
