Compact, key is smooth, comes with reminder coil cable.
That's all you pretty much need to know. This is my second disc lock, my first one was an Abus. I will not buy another Abus lock because of the horrible keys that were a plain pain to use, a hassle to try to fully insert, and even another hassle to turn because I had to keep wiggling it to get it to turn.

The Kryptonite on the other hand has a smooth key that isn't giving me any problems. The lock is small, and although it doesn't come with an alarm, that isn't a big deal. For the price point, it is perfect. And you really can't comment on whether the lock will work down the line unless you set up a hidden cam and bait some thieves with it. Oh well.

It comes with the exact same ORANGE COIL REMINDER CABLE that is sold separately for around 8 dollars. I wish Revzilla printed it on the stats, and I jumped the gun and didn't read any reviews or the Q&A which both state that it comes with a reminder, but that is my bad and no one to blame but myself. But I just wanted you guys to know its the same one that is sold separately (If you haven't guessed, I ordered the separate reminder cable).

Strong and durable
I had the unfortunate experience to have the durability of this lock truly tested by a potential motorcycle thief. I park my motorcycle in a gated garage, but it is shared as I live in an apartment complex. This being the case, I figured I would purchase this lock for some extra security and as a theft deterrent. Unfortunately, after only having my bike for 3 weeks, somebody brought a grinder down into the garage and attempted to grind this lock off of my bike in a theft attempt. They were able to grind through part of my disc rotor, but couldn't do a thing to damage anything on the lock but the paint. The lock is marked all over from the thief attempting various angles, but there is no real damage and the lock works as new. Thanks to this lock, the thief was beaten and I still have my bike! Overall, I highly recommend this lock as a basic level of security, but I will be looking for higher levels of security at this point to prevent further damage to my bike.

As a side note to potential buyers, this lock does come with the reminder cable, so don't worry about purchasing one separately.

Good but description is incorrect
When I bought this I noticed in the description that it didn't mention that it included the lock reminder cord, but did state that it came with a pouch, so I order a cord extra.... I was a little disappointed when I opened it to find that it did in face come with a reminder cord, but no pouch.. I ordered a cord not expecting one so now I have an extra I suppose. I still give it 5 stars because the product is good it was the description that was flawed.

Newer Model
I received the newer model of this lock. Its round shaped and heavier than it looks. Well built and strong as you would expect from Kryptonite.To bad it doesn't specify that is comes with the cable reminder, I bought one as well and spent 8 bucks more. Please correct the description Revzilla.

It Locks
It works. I hook the leash to my rear brake pedal and the lock to the rear wheel brake rotor. The yellow paint seems thin and quickly comes off, but I don't really care. Use the leash! I failed to hook up the leash once, and I started moving the bike, but thankfully it was on flat ground and there was no damage to the bike. I do not know about how easy/difficult it is to defeat, but it is metal not plastic. If I am away from my bike more than 20 minutes, I use this lock, the steering head column lock, and my comprehensive insurance policy. I believe this is the best cost/return ratio you can have.

Great bang for the buck
Let's be honest, Kryptonite products are one of the most well-know in bike safety. With that said, I didn't want anything fancy or over the top and this does the job. Install is simple, product itself it sturdy. My only complaint is that the paint rubs off sooooo easily. But I like how bright it is.

And FYI, it comes with the cable! I ended up buying an extra one not realizing.

Does the job
The only problem I've had is that it got a little rusty on the bolt from getting wet. Other than that, it does what it's supposed to.

Does the job!
Although very small this seems to be a very sturdy theft deterrent. It does come with the reminder cable. The keys that come with it are somewhat unnecessarily long.

high quality security for a very low price
everytime i go out trail riding i use it to prevent a roll away theft, and has worked magnificently on many occasions when people have sat on the bike and tried to move it. thus when the lock hits the caliper they then relies that the bike is not up for grabs

One of the best Nonalarm Disc Locks I've found!
The Kryptonite Disc Lock fits perfectly on my disc and is an excellent deterrent for an everyday thief. I have no doubt that this alone wouldn't stop someone who was determined to steal my bike, but it sure is going to cause them a headache and make them think twice before trying. The finish chips away fairly easily, but I don't care as much about looks as I do functionality. Overall, combined with Revzilla's quick shipping, I am very satisfied and would recommend this to anyone looking for a disc lock.
