Model Description

The Ultimate 420K Mini packs serious security into a smaller footprint. Featuring a 14mm hardened steel shackle and reinforced lock body, it delivers strong resistance against theft. The double-bolt locking system secures both sides of the shackle for added protection, while the compact size makes it easy to carry in a bag or mount to your bike.
