For motorcyclists facing a high risk of theft, the GRANIT Detecto XPlus 8077 2.0 by ABUS is an SRA-approved disc lock designed for premium motorcycles. Its 100 dB 3D alarm does not trigger at the slightest vibration: a deterrent pre-alarm precedes the full alert, preventing false alarms while scaring off thieves. Even better, the alarm function only activates when the lock is positioned on the brake disc, eliminating any accidental triggering during rides. In terms of physical resistance, the main components are made of case-hardened steel with a 19 mm diameter bolt, while the XPlus cylinder repels picking attempts. Made in Germany and supplied with AAA batteries, it installs without compromise.
