This 150 centimeter long ART 4 chain lock from Citycat offers good theft protection for scooters and motorcycles with a high risk of theft. The 10.5 millimeter hardened thick links are covered with a soft nylon cover to prevent damage to the paint. Thanks to the materials used, the chain lock is very robust and resistant to weather influences. For extra ease of use, the key only needs to be turned a quarter turn in the lock to open/close. Motorcycle insurers require an ART slot of at least four stars. Comes with three keys. With information card.
