The disc lock makes a very stable impression and gives me the desired sense of security. The castle just fits so in the rear brake my XV1600, but I always need multiple approaches to the pin then is really splashing around and the lock can also lock. Due to the thickness of the pin and the type of lock, it is certainly not suitable for each brake disc. I was from the pictures or videos on the Internet and not very clever if it does not fit or nu, so I can only recommend everyone to try it easily and possibly convert.
