Xena XX6-Y Stainless Steel Motorcycle Disc Lock Alarm 6mm Push Down Locking Pin

High quality, heavy duty lock that works amazingly.I use this lock to deter the theft of my KTM RC390 while I am out and about. The lock is heavy and strong. There is no way anyone is cutting through this puppy without being noticed. The alarm on the thing is ear piercingly loud. I accidentally set it off in my house at around midnight the first night I got it haha. Talk about mad neighbors. Speaking of the alarm, it will go off when you take it off the bike... only for a moment though. Taking it off takes some getting used to, but after a few practice tries it is easy. Also, I was worried about strong winds setting it off, but that hasn't happened a single timeThe lock does not come with a reminder cable, but I don't see how anyone would forget that they locked their bike up. I usually store it underneath my seat. Occasionally, when I have not used it for a few months, I will hear it going off under there. The sensor will get dusty, and if you have it locked it will go off. A quick wipe does the trick to remedy this.Now, don't buy this product thinking that your bike will never get stolen. There is almost no sure fire way to keep a bike from being stolen. If a thief is good enough, wants it enough, and is prepared enough, your bike is a goner. That being said, this is a must if you want to deter 80% of would be thieves when you are in a rough part of town, or away from you bike a little longer than you feel comfortable with.

I bought this for my 2013 Ninja 300 and it fits comfortably on both fron and rear brake discs. The yellow on the lock is very bright and easy to see so I don't worry too much about leaving it on by accident. The lock is very easy to operate; insert key and turn to the right to unlock (the locking cylinder will pop out), turn key to the left and remove the key, slide the lock onto the brake disc, and push the cylinder in until it clicks. The lock lets out a loud confirmation beep after you put it on.I tested out the siren just to see how loud it is, and even with my helmet on, its significantly loud. It sounds after about 10 seconds of moving the bike around and is fairly sensative to movement.The only thing that I didn't think about when buying this lock, was how I was going to carry it around. The lock is too big to fit the Ninja's storage compartment, so unless I'm carrying a backpack, it goes in my pocket. Just something to think about.Other than that, I definitely feel a little bit more secure having this little guy guard my Ninja. (Oh also fits easily on the CBR 600's brake rotors)I haven't had any experience with other locks and security measures, but I'm liking this so far.

This thing screams bloody murder when you set it off. If I bump into my bike out in the garage it will start beeping so I step back a few feet and cover my ears 'cause it's fixin' to cut loose and howl. Seems pretty tough, very well made, but mostly I like the alarm feature. I'm have fairly significant hearing loss due to the kinds of work I do, loud music, guns and so on...and this thing still hurts my earsA good choice for someone who want's an alarm to use on more than one motorcycle or just doesn't want to mess with installing a full-blown alarm system.

The alarm goes off constantly whether it is activated or not. Simply picking up the lock will cause the alarm to go off. It's hurting my ears and driving my dogs crazy. I contacted Xena product support and haven't heard back from them. There is no phone number for support and you have to send them an email. I just need this thing out of my house. I will never buy anything from Xena again.Update: 12-01-2017Xena product support responded to my email and helped me resolve the issue. The interior alarm module came loose in shipping and that is what caused it to arm and go off. I removed and reseated the module and so far, it has not gone off again. I canceled the return and will test it on the bike.

Well made product. I live in an apartment complex, and it alerts whenever anyone walks by on the sidewalk. 1) I don't use it in the complex because it bothers my neighbors, but 2) it's perfect if I'm out and concerned about my motorcycle in the outdoors. Very happy with it.
