KryptoniteAlarm Disc, Heavy Duty Anti-Theft Motorcycle Lock with 120db Alarm, Weather-Resistant, Powersport Disc Break Lock

Very good ..easy to use.. weight is correct.. the lock functionality is great!! It worth the value .( I would add a plastic cord , just to remember a grown men like me ,that the lock is set …kkkkkkkkkkk!!! ) thanks very much!!

I feel much better using this lock than my alternative securement method. Hefty, solid & secure. Easy to use. Small enough to carry and not be cumbersome. Has an audible alarm (bonus) although I was unable to trigger it 🤷🏻‍♂️. I’m more interested in the locking mechanism and it satisfies my needs.

So far, so good. I have only had this for about a week but so far I really like it. It's sensitive enough that it went off when I tried to test it and roll my bike away. It was so loud inside my garage that I didn't want to be near it and almost left to get hearing protection to shut it off because I really value my hearing. When I tested it after that I used it for sure though. It's loud! I mean, a thief won't drop to the ground covering their ears while screaming and begging for mercy, but it's not fun to be around when it goes off.I do have a few minor complaints that cost it a star. When the alarm goes off it stops pretty quickly, like within 30 seconds-quickly. I'm not gonna go test it again, but it's not a long alarm. It does reset and will go off again, but I think it will just stop after 15 seconds or whatever it is. I also had a really hard time putting the battery in. I had to make a little plastic slide to hold the spring back while I pushed really hard to get the battery in. I'm not sure how I'll get it out and I might actually contact Kryptonite about it.I am using this on my E Ride Pro SS and it fits on both front and rear rotors.

This lock does have an alarm, but unlike others a stiff breeze will not set it off. It will go off if you try to move the bike or start messing with the lock itself, and that is all i was looking for. Would have liked a slightly larger pin that goes through the disc, but what is there is satisfactory. The one big change i would like to see is to make it available in a bright color instead of black and chrome. I want potential thieves to spot it before even coming over to my moto, especially since i lock it on the rear disc. The colored reminder cable form the lock to the handlebar help with that, but all the same, a bright color on the lock itself is better. It has been on the bike in rain and snow and i have never had a problem with water getting in the battery compartment or with corrosion. I also like the one beep for locked and two for unlocked. Very simple. It also fits perfectly under the seat of my Versys 1000. Overall i am very satisfied with the product and would purchase again.

Excellent product especially used regular type key if you don’t mind paying the price.

Like the ease of use, loudness of the alarm but installing the battery is a total pain. Use caution and patience and eventually you'll get the battery seated.

The media could not be loaded. Does not work. Simple as that. I am on my 2nd one now exchanging it for a 3rd. The alarm will arm itself properly maybe 1 out of 10 times that it is locked (i’m being generous). Its a piece of junk, save your money and buy another brand or one that is just a lock because all that this one is. :( 👎

Heavy duty. Loud ear piercing sound. Will have to wait and see if it goes off. Neighbors know it's being parked for the winter. Depending on how you apply it determines if wheel can still spin even partially. Turns on automatically once pin is extended through brake disc.
