Theft protection with alarm. The SRA-approved ABUS brake disc lock GRANIT™ Detecto XPlus 8077 2.0 sets standards in terms of quality, protection, and comfort. An intelligent alarm reliably protects the motorcycle from theft. To prevent the full 100 dB alarm from sounding at every minor movement, the lock emits a short pre-alarm for small vibrations. This draws attention and deters potential thieves from their intentions. To ensure that the lock does not trigger an alarm during transport due to vibrations, it features a brake disc detection system: the alarm function is only active when the lock is mounted on your bike's brake disc. In addition to the alarm, the high-quality and robust material provides an extra layer of protection: the most important components are made of hardened steel, and the bolt has a strong diameter of 19 mm. And if someone attempts to pick the lock using delicate methods, the ABUS XPlus cylinder resists manipulation attempts such as picking.
