Campos: Buen producto, funcionando bien hasta el momento, se ve robusto, me gustaría que el mecanismo no se sintiera que se traba.

Perk: Lock functions as expected. Well made, durable, and when I forgot it was on and I tried to back out, I couldn't. So, it definitely does what it is supposed to do...

Stinkysquishy: I originally wanted to return this as it is soooo heavy, I felt there was no way I'd pack it with me while moto camping.

However, the lock does serve a good purpose as it's incredibly thick and - I'm assuming - very secure against theft. It has given me the confidence to leave my bike locked on the motorcycle rack or trailer, or even when I'm at a hotel/motel in distant locales before leaving on my camping trips.

My KTM 690 Enduro has a steering lock feature. If you install this lock on the rear disk rotor in combination with the factory front steering lock, thieves really can't move your bike without lifting it and putting it on a trailer/in a truck.

For that reason, I'm giving it 4 stars. If it were lighter and more easily packed, I'd give it 5.

Bryan: Not sure how much I can contribute here, but it is definitely a big, robust lock. It is surprisingly lightweight, but still seems solid. No, I have not taken an angle grinder to it, and my lock picking skills are not up to par for a proper test so I can't comment on actual security, but I feel it is a good match for my Schlage 12MM cinch chains. It is plenty to keep from being an easy target.

I also appreciate it comes with 3 keys.

Sam D.: I bought this lock specifically to use as the locking link for a Schlage 12mm cinch-ring security chain. As with most Kryponite locks, it is tough and well made.

This Kryptonite/Schlage chain combo is primarily for securing our mountain bikes on my truck during one of those bike trips that I end up parking and leaving the truck at public places for an errand or something. Keep in mind though, this or any other brand of lock/chain combo isn’t foolproof where you lock your bike on a lamppost and leave it overnight on the street. To a determined thief there’s no such thing as an unbreakable lock or chain.

That being said, this lock/chain combo should be tough enough and prove to be difficult for a thief to make a quick steal of your bike, especially if it’s on a visible high-traffic location. The combo is also intimidating enough to discourage these criminals and look for a target elsewhere.

Ben Bell: This is an awesome disc lock for motorcycles! It's small enough to be carried around easily, but burly enough to look and feel solid when locked on the bike. I use it to attach my chain to the bike in bad parts of town, and I also use it just by itself when I'm on the go and don't want to carry a chain. I like the yellow color because it's bright enough to act as a deterrent, in addition to making my bike more of a pain in the rear to steal. It comes with three keys (one lighted) and all work great, plus it has a unique serial number so you can have new keys made in case these are lost. The lock mechanism is smooth and easily accessible (a BIG plus if you've ever messed with disc locks before) and I just lube it every couple weeks and it been quiet and efficient. The shackle is nice and wide, so it will fit around most discs on most bikes and still have space to add a chain, but its also very thick (good for resisting cutting) but trouble if your disc has only small holes in it. That being said, I can also throw this around the rear sprocket with no issues, and the rubber coating is nice and protective so it doesn't damage the bike.

This has become something I use several...
