This lock is a pretty beefy lock, which is pretty comforting when you are depending on it to protect your precious motorcycle! Finding just the right spot to slide it through the disk isn't always the easiest and the plastic scuffs just a bit, but nothing that is going to affect the real application of the lock. The provided keys worked great and you have five of them, so hopefully it should be impossible to never know where at least one of them are! It's a great lock. (I used mine on a dirt bike if anyone was wondering if you could do such a thing)
I bought this lock to secure my street bike, and let me tell you, this thing is big, thick and tough. it would take hours to hack saw through, and the keys are very odd shaped and looks to be impossible to pick. not to worry though you get 5 keys with the lock and a code card so you can call akita and order more. it's a great lock.
