Freddie L on Jun 1, 2016
For protection when in the city, however it is overly sensitive and I don't ever use now.
Danny B on May 6, 2016
Even with theft insurance I still wanted a great locking and alarm system.

Basic security with alarm perfect for what I need to provide peace of mind
Rodney S on Dec 1, 2015
Needs something visible to hopefully deter thieves and something audible to attract attention should they not be initially detered.
Rudolph B on Jun 30, 2015
The alarm feature attracted me.
Daniel C on Jun 28, 2015
Wanted small, cost effective alarm to use when traveling and staying overnight away from home. Much simpler than installing full alarm system and should be just as effective. Wish there was a pager option though.
John M on Jun 8, 2015

Russell D on Apr 8, 2015
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
Affordable and reliable disk lock to help deter thieves.
Brandon H on Mar 16, 2015
i choose this xena XX-6 so that i could have some peace of mind that my bike will be there when i get back, but this is obviously not full proof because a bike can easily be picked up.
wilian r on Feb 25, 2015
I choose the Xena XX-6 Disc lock after researching lots and lots of reviews of disc lock and found this one to be the best.
Dennis B on Dec 1, 2014
Good reviews and very visible.
Mark G on Sep 29, 2014
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.
Alex S on Sep 15, 2014
I choose this because I want to feel safer whenever my bike is parked on the street.
Eleazar H on Sep 7, 2014
Prefer smaller form factor and seems good enough.
Leslie S on Aug 28, 2014
small package and it's loud!
Noel R on Aug 13, 2014
to increase security on the bike. liked that alarm goes off on movement...but not much help if i don't hear it :)
LDNYC on Jul 9, 2014
Color and price - perfect
Evgeny N on Jun 23, 2014
To alert my dog when the alarm goes off, he goes straight to the glass door when the alarm sounds.

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

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,
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.
