Kryptonite Keeper Disc Lock 4.6 5 54 54
Excellent lock Simple to use, not too heavy considering what it is (isn't noticeable in the backpack), has a really durable look, kind of an old fashioned heavy duty piece of equipment like in the good ol days! Only complaint is... The lock reminder that came with it... It wasn't advertised as having come with it, so I bought an extra one. Not a problem as I use it with a separate cable lock I also bought, just interesting that there was no mention of it coming with the reminder from when I remember. It's a little tight squeeze to get it on my little disc brake with ABS on my Ninja 300, but it works if I line it up with the groove. That's mainly because the reminder gives me less room to work with. Maybe make these slightly longer to account for abs larger disc brakes? May 26, 2016
Two thumbs up Great little lock, I feel a lot safer leaving my bike parked on the street with this on it to deter the average thief. The lock feels really solid and is incredibly easy to install and remove and the reminder cable definitely comes in handy. The paint is a little weak and after dropping it once from ~6in. onto pavement there were a lot of scuffs and chips. It doesn't bother me much but just don't expect it to stay pretty forever.

Great Value Peace of mind is priceless. This lock is a great value, super easy install, comes with two keys, fit my Honda Scrambler perfectly. I learned how durable it was when I ran it over with my car and it survived with no damage. May 17, 2016
Does what it's suppose to It feels sturdy yet light. No problems fitting this lock on the front and rear calipers. It stores perfectly in the storage compartment also. The chrome finish is nice but I haven't dropped it yet. I think it's a good deterrent for amateur thieves. Having one for the front and rear calipers would definitely be beneficial. May 10, 2016
So far, so good This lock is Hefty. It feels heavy, strong, and well-constructed. There doesn't seem to be anyway, without damaging the disc, that you would be able to get a blade in between the lock and the disc in order to cut the PIN. That had been my biggest concern. To me that seemed like the weakest link. I'm not worried about that, anymore. May 3, 2016
Good quality for the money The Kryptonite Keeper 5-S is a good low budget disc lock. It seems very sturdy and the piston works really well. The seal (cap) is good if you leave you bike in the rain. April 12, 2016
2015 dr200 security This bike lock is so solid you can feel the quality in weight, plenty of brake caliper room that I could easily fit two brake calipers side by side in and lock so I know I can trust it for my future investments. Shipping was to the dot April 12, 2016
Lock and Stock This product does what it was intended to do. It's perfect for my Yamaha FZ-07. I lock it on the rear disk and hook the reminder cable on the throttle. I was able to squeeze it under my seat after removing (even with the manual and toolkit sharing the space) which makes it really convenient if you don't want to carry a backpack around everywhere you go.
