Abstract: A lock for a motorcycle has a generally U-shaped construction. The open end of the U is slipped over the brake rotor of the front wheel or the sprocket of the rear wheel of the motorcycle. A bolt then extends across the open end of the U-12 shape to hold the device in place. This bolt is engaged by a spring loaded pin so as to hold it in position. Rotation of the wheels is then prevented by contact between the lock and the brake calipers on the front wheel or the chain or sprocket on the rear wheel. In order to release the bolt, a cam and a spring biasing the pin in the opposite direction are provided so that rotation of the cam allows the pin to be withdrawn from the bolt. The lock includes a lock-out mechanism which prevents the motorcycle from being started when the lock is in place because the lock-out mechanism retains the ignition key. In addition to the lock, a single loop cable can be provided for attachment about a stationary object and received within a channel in the lock.
