Simply park your scooter, attach the brake disc lock and that's it: The 304 makes securing your motorcycle a simple task. The 10mm locking bolt made of specially hardened steel and the impact-resistant cast metal lock body are excellent deterrents to thieves. The ABUS quality cylinder of the 303 makes unauthorised access anything but easy. The user-friendly automatic locking mechanism makes daily use enjoyable: just push the button and your bike is secure. The keyhole also comes with a manually operated cover to prevent dirt and corrosion from damaging the device.
