I have a 2007 Ninja 250 and it fits the disc perfectly. There is about 3/4 inch between the washer and the end of the slot in the lock when I let it hang straight down. Feels very durable. Getting it to unlock was difficult at first, but once you get the hang of it, it becomes easy. A few reviewers have mentioned that they had trouble picking the lock after being exposed to the elements for a while, so I sprayed the keyhole with WD40 and did it from time to time to protect it from rusting. I can't expect much from a lock of this price. Also, the logo is very easy to remove. I can scratch it with my fingernail so I doubt the strength of the lock but it seems very strong and with a little WD40 in the key slot it should hold up fine.
