Sometimes an expensive lock can be placed in such a way , that it is easy and fast to break and on the other hand, placing it in a specific place or manner, can make it quite a lot more difficult to break.
Disc locks have there limitations. ( All locks do). The bike can still be lifted, because they do not secure it to an anchor point.
But they are usually also easy to break with a small tool called a bolt screw extractor.
One of the many video's online :
Also, when mounting it on the front disc, that disc can easily be unbolted.
So I had a look at my bike and I think placing the disclock on the rear sprocket, will make it a hell more difficult if not impossible to use a bolt screw extractor, or even an angle grinder or saw on it, at least not without damaging vital parts of the motorcycle. It is also near impossible to get that rearsprocket unbolted with the disclock on it.
SO, what are your thoughts? Does it make it a little more tricky for the thieves?
