On every motorcycle and scooter, there is little storage space and yet each requires protection against theft and unauthorized use. So what is the anti-theft that every biker can always carry in normal time? Disc blockers are the practical solution for many of two motor-driven wheels. They are compact, lightweight and thus easily transportable. In the case of a long parking time with a high risk of theft, we recommend a combination with a chain so that the bike cannot be carried away.
