With the Trigger Alarm 350, you enjoy security in two ways: through ABUS locking technology and a loud 100 dB alarm signal. The locking bolt of the Trigger Alarm 350 is made of 10 mm hardened special steel, making it very robust. The housing and load-bearing parts of the locking mechanism are also made from the same tough material. The ABUS "push down" cylinder is easy to operate and automatically locks the bolt. Additionally, the Trigger Alarm 350 disc brake lock protects your scooter or lightweight motorcycle with an electronic alarm unit that is triggered by a shock sensor. Just lock it, set it to "On," and you'll immediately be alerted if someone tries to tamper with your bike.
