KryptoniteEvolution Compact Disc Lock, 13mm Hardened Max-Performance Steel Shackle, Sold Secure Gold and Art 4-Star, High-Security Anti-Theft Orange Bike Lock, Includes 3 Stainless Steel Keys

Super solid, it looks and feels secure and durable. The key cannot be removed unless the lock is properly closed, which gives you peace of mind that it’s securely locked. On my Benelli TRK251, I couldn’t attach it to the brake discs as it doesn’t fit properly, but fortunately, it fits perfectly on the sprocket. This makes it much safer and leaves very little space between the lock and the sprocket, reducing the likelihood of using a lever or tool to tamper with it. The only downside is that since I can only attach it to the sprocket, I sometimes get grease on my hands, but it’s nothing major. Very happy with the product!

None of these are "small" but this one is pretty compact to fit in a pocket. Should fit pretty well around your disc and provides pretty good security (with the understanding that if they want your bike, they're going to find a way to steal it) it certainly works well as a deterrent, and piece of mind if you run into a store. I'm happy with the purchase.

I hope to never find out if this works well, but it looks to be well made and I have their other locks, which I've also been impressed by. LPL seems to like Kryptonite products, so that's a good indicator of their quality.

Works just as intended. Very easy to setup, pretty straightforward. I like the included cable to remind you and an extra pair of keys! The small portable form factor is very convenient.I had a slight hiccup via one of the keys, and contacted them via their official website. The customer service was beyond amazing. Problem was rectified.Highly recommend this brand.

Works well. Struggle to get key in sometimes

I'd give this lock a 12 out of 10. It would be extremely difficult and time consuming to attempt to cut this lock and it's a very compact size to keep stored in my tank bag when riding

I installed this lock on my the brake rotor of my Ninja 400 in the afternoon. Fast-forward just a few hours to 2:30 in the morning, a couple of would-be thieves approach my motorcycle with flashlights and started checking it out. As soon as they saw this beefy lock on the wheel, the turned and walked away. This lock is very sturdy and I do not think it could be easily broken or removed without also damaging the bike to the point it would be unrideable. It is also very compact and easily fits under the rear seat of my bike. I would highly recommend this for anyone with a motorcycle in an urban area who can't store their bike indoors or have it chained to something secure.

Muy poderoso es liviano y se ve de gran calidad
