Harley-Davidson SIREN DISC BRAKE LOCK

The Harley-Davidson Siren Disc Lock is designed to prevent roll-away theft by combining mechanical security with a powerful audible alarm. When the motorcycle is moved, the 120dB alarm is triggered, providing a clear deterrent to potential thieves. For situations where only mechanical security is needed, the alarm can be easily deactivated with the key. Made with a 6 mm hardened-steel locking pin and corrosion-resistant construction, this lock is durable and reliable. It comes complete with two keys, a high-visibility reminder cord, and a Lithium (CR2) battery, offering both security and peace of mind.
