Small & compact, but with a loud effect. Thanks to a vibration sensor, your lock will sound the alarm as soon as someone tampers with your motorcycle without authorization. What s better than a secure lock? A secure lock with an alarm function. Once you activate the alarm sound on your lock, your lock is armed. In the event of a sustained vibration to the lock, it will emit a 100 d B alarm signal. Should you ever want to use your lock without the alarm function, a 5 mm locking bolt made from specially hardened steel secures your bike. The ABUS "push down" cylinder is easy to use & locks the bolt automatically. In case you ever misplace the key, three keys are included.
