The padlock is huge and heavy. Unfortunately, it does not fit under the couch. The selective part is made of an impressive cheap plastic. The pin can be inserted in two ways arming the alarm or not. The fit of the parts is very good. Nothing squeaks when you squeeze the plastic parts. On the underside of the movable lock protection from dirt. The alarm is quite loud. Before switching on, it signals the activation of the motion sensor.
Yamaha XJ6 Custom. The lock is suitable for newer discs so I mount it on the rear. For aesthetics -1 because the photo shows a version with a red band, and came with an arrow version, which is less visible. Plus it is an older version from a few years ago.
The alarm itself does not go off falsely so great! I recommend as a variety of fasteners!
BMW GS 1250 - a sturdy lock, I watched several videos on Youtube and chose it for the best parameters and resistance to possible theft attempts. Thick steel should resist hammers, scissors and secateurs. Plus the loud alarm. It will work especially as a deterrent abroad.
