Peace of mind When I'm far from home and two guys could push my ride onto a trailer while I sleep...a solid block of metal attached to the brake rotor lets me sleep a little easier. I don't know how you'd defeat this unless you picked the lock, it's heavy and there's no access to the pin. I carry it in my tank bag and put it on when I go in for the night. March 29, 2015
Does the job! Although very small this seems to be a very sturdy theft deterrent. It does come with the reminder cable. The keys that come with it are somewhat unnecessarily long. March 16, 2015
Great for what I wanted Lock is solid and is really great that it comes along with the reminder cable. I live in SF and I just need a little extra to make me feel safe about my bike as it was almost stolen before. Although I'm sure the lock could be broken its a bright yellow deterrent that says "hey I'm more work then you want to go through". I'm very happy with the lock and would easily buy another one or recommend it. That being said I will say that the dusk cover doesn't go in very well and tends to just "flip" out. And although I've only been using it the last month the yellow paint on the inside has already started scraping off. I bought two locks for myself and my girlfriend; to not mix them up I added a strip of red nail polish on one and found that rubbing alcohol will strip the yellow paint off a little. March 2, 2015
Good solid lock This is the first disc lock i've ever bought and am satisfied with it. It is solid and the lock works very smoothly. My favorite feature is the rubber key seal the keeps lock from oxidizing or getting jammed with debris. Foer the price its a great buy. Make sure you get the right size pin because i got a smaller size pin and should have gotten a larger diameter pin. November 24, 2014
Simple disc lock It's a very simple lock. The pin is small and the 'body' is bulky and hard. I would suggest to always park on 1st gear, lock the bar and use a motorcycle cover. If you forget about the disc and try to roll out your bike, or worse, actually ride it, you are going to have a damaged disc, if not, a lame fall. If a thief try to take it, will have to deal with locked bar, finding neutral and braking the lock. Anyways, it is more a psychological relief than an actual safety device, in my situation.

Good build quality. Protection to portability all in one. The paint chips off quite easily, I have it stored in the passenger seat compartment and it touched some bare metal. No biggy. It's very tough and feels very solid. I doubt anyone would be able to break this off easily. It's a piece of mind and the fact that it's so small you can bring it quite easily. November 21, 2014
Easy to use...period Super easy to use and cable that comes with has a dual purpose to secure riding apparel just by using the helmet lock under the seat...I love it August 25, 2014
great bang for the buck Everything can be stolen. The bright yellow will help deter thieves from your bike. This will really help slow down any potential threat with its heavy duty constriction. Way more portable and usable than a cable lock. June 23, 2014
