The ABUS Granit Detecto X-Plus 8077 2.0 is a solid choice for a motorcycle brake disc lock with an integrated alarm. Its alarm is quite loud at 100 dB, effectively deterring thieves. The alarm system is smart, offering a two-step warning: a movement-triggered pre-alarm followed by a full alarm if more movement is detected. This sensitivity setup helps avoid false alarms while staying alert to real threats.

The lock is made from hardened steel, providing strong physical protection against tampering or cutting attempts. While specific water resistance details are not provided, ABUS products are known for durability in typical outdoor conditions. Installation is straightforward as it functions as a rim lock—just attach it to your motorcycle’s brake disc. The transport mode feature allows moving the bike with the lock engaged without triggering the alarm. The bright orange color enhances visibility, reducing the chance of accidentally trying to ride off with the lock still on.

One limitation is the lack of smart home or app connectivity, so all control is manual via touch. This lock suits riders who want a reliable, durable alarm system integrated into a physical lock without the complexity of extra technology, prioritizing strong protection and clear alarm signals over remote monitoring.

It is also resistant to physical damage and weather conditions, ensuring reliability in different environments. The lock includes six internal batteries and six backup batteries, which extend its usage time. Additionally, an Allen wrench and carry pouch are provided for convenience.

It is worth noting that the item is relatively small and lightweight, at 12.3 ounces and dimensions of 3 x 2.8 x 1 inches, which might make it less intimidating to potential thieves. Also, installation might require some practice, especially for users not familiar with disc brake locks. The inclusion of a reminder cable helps prevent accidental riding with the lock engaged.

Additional features like the vehicle search function with 3 kinds of bells can help locate your bike in crowded parking lots. The alarm's compact dimensions make it suitable for bikes, electric bikes, motorcycles, and scooters.

However, the battery-powered nature might require periodic replacements, which could be a minor inconvenience. Additionally, while the alarm is effective, the remote control range might not be sufficient for very large areas.
