Storage space on a motorcycle or scooter is scarce and, even so, everyone needs protection from theft and illicit use. What lock can a rider always carry in normal cases? Disc padlocks are a practical solution for many motorized two-wheelers. They are very compact, lightweight and, therefore, very easy to transport. For a prolonged parking lot with a high risk of theft, the combination with a chain is recommended so that the motorcycle can not be taken from the site.
