If you are worried about this lock holding up in a theft attempt...

Recently had someone try breaking the lock, which I use with the chain to secure my motorcycle to my carport. I didn't even notice the lock had been tampered with at first until I saw the plastic cover had been broken off, which I thought might have been a result of the recent stormy weather we had. It wasn't until I noticed the extent of the damage that I realized someone had tried stealing my bike. Not only did the lock hold up enough to prevent this, it also remained functional. I was able to unlock my chain, though it took some added effort compared to a intact lock, to send my bike off for service. Bought a replacement lock, but I will keep the beat up lock to use as a disc lock.

Good Starting Point

I purchased this lock after looking at many different Xena and Kryptonite models. I decided that I wanted a non-alarmed quality disc lock that I could add a chain to later. I decided for my entry level bike, this lock was the right fit. Many people wrote that the cable reminder included with the deluxe kit is short. For my Cbr500r, it's plenty long and the lock is smooth. Also, it packs well in my tail section.

Heavy Duty

This works perfectly for locking up my bike, I thread it through the sprocket. Very heavy duty, gives peace of mind. It’s heavy so not something I’d want to carry in my pocket so I just keep it in my bike luggage.

Perfect for price.

I bought the premium pack comes with; 3 keys (one has a small LED flashlight), a orange reminder cable (a must with a disc lock in my opinion), and a small carrying pouch. Lock feels solid and of good quality. The lock itself is bigger than I expected, the loop portion just barely fits through the front disc on my sportster. For $50 you can't beat it, provides peace of mind while leaving my bike unattended in the parking lot at work.

It's a lock.

I hope I don't have to find out how well it can stand up to thieves. Feels very heavy duty and I feel safe when I park my bike at work.
