Exactly what I wanted
Super easy to use and straight forward.

It is not as sensitive as I was expecting (which is good), since so many people were complaining about how sensitive it was. Alarm does not go off just because I touch the bike. I can easily get on the bike without the alarm going off. Of course once I move the wheel or turn the handles then the alarm will give off the warning beeps.

It was difficult to put the pin through the brake disc at first, but you just have to get use to it. Perfect little disc lock and exactly what I was looking for. It gives me a piece of mind when I go to certain places.

Great concept, but the alarm is starting to arm itself for no reason causing huge amount of embarrassment whenever you ride your motorcycle.

Good Deterrent but Lacks Solid Build
I mainly purchased this lock as a deterrent device and I think it did a pretty good job in that regard. However, it lacks solid construction in my opinion. I had the lock installed on my rear brake rotor and like a dummy forgot it was on the rotor when I came to back my bike out of my parking spot. I started backing up the bike and felt a thunk. I looked down and the lock was on the ground. No damage had been done to my bike at all but the lock was toast. It bent open and the pin would no longer reach the bottom of the lock. I was surprised that such a substantial looking lock would come right off and not prevent the bike from being walked backwards. I think most thieves would have figured out this trick by now. I will say though, that I did remove the alarm battery from the lock since I live in a very motorcycle heavy country. Perhaps if I left it in I would have been warned it was still on in time to not hit the caliper. However, I didn't want it going off all the time if someone needed to move my bike to park next to me. So would I buy it again. Maybe. Would I recommend it. I suppose. If you just want something to make the other bike look more appealing and easy to steal then it works.

I was debating to purchase this or not but I'm glad I did. I read some of the reviews before buying and most of the reviews were annoyed because of how loud and sensitive this disc lock alarm is. To me, that is exactly what you would want for your motorcycle. What's the point of buying a lock with an alarm if you don't want it to be sensitive and loud? The whole point of it is to alert you when something/ some one touches your motorcycle and it does such a good job at it that I am very very happy that I purchased this.

Kinda disappointing
I'm sorry, but there is no way this is 120dB, even with a fresh battery out of the package. The crazy thing went off while tucked in the back seat during a ride last week and I could barely hear it. My motorcycle is right outside by bedroom and the wind made it go off while parked (will come back to that) and even still I barely heard it. Couldn't imagine trusting this with my bike in the driveway. It's a great disc lock, a terrible alarm. On that subject, this seems way less sensitive and reliable than the next line up. I can partially remove my cover AND stick the key in the disc lock before it detects motion which is FRIGHTENING especially because I use it in the 12 o'clock position which is it's most sensitive. But somehow the strong winds this Sunday set it off multiple times -_- I don't think this alarm will have you or the neighbors waking up in the middle of the night. On the other end, the one I got is bright yellow and is still an impressive disc lock. I would not rely on the alarm if you're leaving your bike out on the street or in the driveway.

Great little lock alarm
Worth every penny! I feel so much better parking on the street now. The alarm is perfect. It's not overly sensitive and the bright yellow paint is an automatic warning to any shady characters. When it goes off it's loud as hell! Also it's small enough that I can store it under my passenger seat of my Yamaha FZ-07 which is a tiny compartment.

First line in security
I use two, one for each wheel. At my residence, I use the chain attachments available to chain (hardened steel) secure it around a pole. I also have a 2-way alarm, gps locator and cover alarm. I keep it covered at home overnight. I use many deterrents to discourage thieves so I won't have to beat someone to death

This alarm fits my bike and does exactly what I need it to do, deter theft. It's very loud, and easy to put on. I sometimes have trouble getting it unlocked so the alarm has gone off on me a few times which is embarrassing, but I have had no problems with false alarms. I set it on my front caliper at about 1 o'clock and it seems to work great.
Brian R on Mar 18, 2015

You can never have enough security on the road for a super touring bike. Went with this one on recommendation from one of Revzilla's gear guys. Works like a charm.
Daniel C on Sep 23, 2014
I chose this because it can fit thru the rear rotor vent hole. It looks awesome and indestructible. I plan on complimenting it with the XX14 for the front rotor soon to replace the Kryptonite I already have. These are the "Nth" layer to my bike security.

Will this fit a 2012 kawasaki ninja 250? What would the loudness of the alarm noise compare too?
A shopper on Feb 7, 2015
BEST ANSWER: It will fit on a 2nd Gen Ninja 250R 2008+, but the entire brake disc will be in the opening of the lock. It will NOT fit in the vent holes.
Does vibrations or louder exhausts from other motorcycles set off the alarm?
A shopper on Apr 28, 2011
BEST ANSWER: thought this is a good question since I only just got my lock. set the lock on my bike and had a noisy hog gun it. set off the neighbors car alarm but not the bikes. aimed the pipe right at it and it didn't react till the almost touching the lock. do not bump the bike or jiggle the stearing it or the alarm will go off. I 'm now deaf so no more Mr. Experiment today.
I noticed while testing this product moving it around about my house the alarm will sound whether locked or unlocked. How do you ride with this in a backpack or something similar without the alarm sounding? i can't seem to find a way to achieve walking around with it without the alarm going off. thanks
A shopper on May 1, 2014
BEST ANSWER: The alarm is activated once you press down the cylinder which is also the key hole. You can turn and lock the device without pushing the cylinder down while its in your back pack I do it all the time. The only time it needs to be down is when in use. If your device is still sounding an alarm with the key hole cylinder in the raised position then you have a defective device and should seek out warranty services.
I have this and have been using it for about 10months. Seems the battery is starting to die, what is the process for replacing the battery and can I order it from Revzilla? Is it a specialty battery?
A shopper on Feb 10, 2014
BEST ANSWER: The type of battery you need is a CR2 3v Lithium Battery type, so you can purchase at almost any local store. Installation is easy but I recommend using earplugs when changing the battery. You can also find the manual for Xena XX-6 online. Google: Xena XX-6 manual

Thanks
does it fit a 2007 gsxr 600?
A shopper on Apr 28, 2014
BEST ANSWER: Yes it does fit. It should fit most bikes. I sold my Gsxr a while back. Now I have a cbr1000rr and it still fits on my current bike
Would this lock fit on any bike? More Specifically, a 2007 Yamaha FZ6?
Diego U on Mar 27, 2014
BEST ANSWER: If you have disc brakes with holes, probably yes.
Does the locking pin on the XX6 fit through the vent holes on a 2nd generation Ninja 250R?
Hao D on Sep 9, 2013
BEST ANSWER: Hi Hao, forgive me, I have an '08 Yam Fazer 1000 with stock discs and I thought the vent holes on Japs if not most modern bikes would be standard. I bought it without worry of that since the Xena specs on their site didn't mention any make or model that you had to specify before purchasing.
That being said, I believe you're pretty safe in getting the XX-6. I got the silver and wished I got the yellow just to give it that extra deterrence. Its very loud and the sensitivity is good enough to not go off unless the bike is intentionally shaken or moved. Passing vehicles on the road shouldn't set it off but if it does, it is not going to stay on forever.
A great security buy.
I also fitted a Spy 5000 remote start alarm with motion sensor but I use the Xena more. It just might be all you need.
does the cover being blown around by the wind ever make it go off?
A C on Mar 2, 2016
BEST ANSWER: The cover moving slightly should not set it off. If the wind is strong enough to shake the bike however, it might go off. In my experience, one has to move the forks or nudge the bike to trip the alarm.
I have a 1996 Harley Davidson Sportster 883. I believe it has stock discs. Would you happen to know which of the XX series locks would fit?
Kelvin C on Jun 13, 2014
BEST ANSWER: It appears the XX-6 Should fit your disc-lock in addition to many other size Disc locks offered by Xena. You can confirm on Xena's site which allows you to search your bike model.
Hello! I am trying to see which one of these Xena locks would fit my bike. it's a SYM Wolf Classic 150 - a small 150 cc bike, front brake is 240mm, rear 130mm. Any ideas on which Xena lock would fit best?
Thank you,
f
A shopper on Jul 8, 2012
BEST ANSWER: Go to the Xena website you can print off a template that has all the thickness of the lock throats and their depth along with the pin size. just cut it out and slap it on on the disc brake it tells you which locks will fit.
