Siren Disc Brake Lock

Designed to discourage roll-away theft, this rugged lock easily attaches to your disc brake and sounds a piercing alarm if the motorcycle is moved.
Physical movement triggers a piercing 120dB audible alarm that acts as an additional theft deterrent.
Audible alarm can be deactivated by key if only mechanical security is desired.
0.23 in (6 mm) diameter hardened-steel locking pin.
Corrosion resistant.
Includes two keys, high visibility reminder cord, and Lithium (CR2) battery
