Kryptonite Keeper 5-S2 Disc Lock - Chrome | Kryptonite Keeper 5-S2 Disc Lock with Reminder Cable, 5.5mm Security

Got smashed by concrete when someone tried to steal my bike but lock did not break. Got some damage but still usable. Kept using until i had to buy a new one when it got cut by a professional saw.

Easy to use, works fine on Vespa GTS300

Works, good quality

This disk lock has been easy to use so far, no issue with the mechanism and easy to put in place. I appreciate that it comes with a reminder cable and also that it fits under the rear seat of my motorcycle. It also feels solid and is pretty hefty, there is a good weight to it. However I am removing a star because the paint chips off very easily. I put the lock in a plastic pouch to prevent that from happening, but even minor bumps seem to chip the paint.

Just got it last night. I was very surprised when I opened it. How well made it was. I’m sure it will be a very good deterrent from theft.

These disk locks are the best I've found. Simple and sturdy. The tether line I always run to the left handlebar to remind me that the damned thing is on the disk so I don't try to ride away and cause damage. I have 4 of these locks on old airheads.

So someone did try to steal my motorcycle, but I had this lock on the rotor. In the pictures, you can see they smashed the tire lock, freeing the handlebars to rotate without the key. They tried to disassemble the tire (you can see a missing bolt) to get the lock off so they could roll the bike away. When all that failed, they smashed the gas tank in an attempt to get the gas cap off, and when all that failed, they kept my tarp as a booby prize. The lock held. You can see how much abuse they gave it, and I was worried for my rotor, but it held the thief up long enough for a neighbor to drive him off. Job well done, 5/5 buying the name brand was worth every cent. My only minor gripe is that the rubber cap to protect the keyhole from rust has never wanted to fit right, but my area doesn't have much corrosion as a concern. I've told everyone I know that rides to get one! It fits in your backpack and takes only a few seconds to put on. I don't use the strap because I don't want to draw attention to the security device, but other people do to remind them to remove it before sitting down and firing up. Either way, excellent product, would absolutely buy again, but everything is still here and I don't have to because it did its job.

Solid worth the money

Einfache Handhabung, erfüllt den Zweck.

Love it. !!!!! The key gets hard to get in but not an issue

Best lock company out there. My old oxford lock rusted and had be cut off. This lock from Kryptonite, takes so much abuse, always works, never rusts, feels very secure.

Great disc locking device for my bike, it’s easy to use and very convenient and convenient to carry around and prevent any theft off my ride

Definitivamente el Mejor candado que he tenido ! Tiene llave de seguridad ó sea no lo cierras sin la llave es muy fuerte y pesado, no tiene alarma eso está bien porque no siempre que lo cierras es para asegurar algo,no es el Más barato pero para el disco d la moto cumple bien
