Xena XX-6 Disc Lock 4.4 5 65 65
better then i thought it would be alarm is louder then you would think in a good way. extra peace of mind. April 17, 2014
This disk lock alarm is awesome! Perfect for traveling or just keeping the bike a little safer while it sits outside at the house! I did a video review on this product because I was so happy with the purchase! Thanks again for another great product Revzilla! April 10, 2014
Disc lock that you can't go wrong with! Easy to use and fits good! With or without the alarm, it is a great lock by itself and does its job! Wish it came with a storage back because it gets a little dirty and I usually put it in my backpack and it gets on my other stuff. December 3, 2013
Not that loud... I bought this lock since my rear wheel can't accommodate a bigger peg. The 6mm isn't really that confidence inspiring nor is the alarm on this thing. People say it's super loud but it seems like it would get the attention of people nearby but not really that loud. It only goes for 15 seconds which doesn't do too much imho but I use it everyday and it's really easy to put on. Big negative I've found so far is that the key hole kinda slides around so the key doesn't go in easily all the time (the topmost layer rotates independent of the rest of the locking mechanism) which leaves me scrambling to open it while the alarm goes off. October 31, 2013
Basic protection is better than nothing... This thing can wake the neighbors up if triggered; however it does take a little bit of bike movement to get the alarm to sound. Overall it's a good product for a reasonable price to rid you of the common bike thief, but it's definitely no safeguard against real criminals. Pros: Easy to install Sturdy Loud, when triggered Bright yellow color avail; really stands out Reasonably priced Cons: Sometimes key gets jammed when locking/unlocking Isn't very sensitive at all October 29, 2013
Great product but lack some this product offers a lot. One thing i dont like about it is that the sensor arent sensitive enough. Maybe mine is just a lemon October 28, 2013
Decent disc lock, questionable alarm. The disc lock feature fits my CBR 250 front disc perfectly. No issues lining it up at all. The alarm leaves a bit to be desired. I tested my alarm by moving my bike and it went through the series of chirps (5), then the alarm just did one final beep and... nothing. I changed the battery, but this did not resolve the issue. The alarm just doesn't go off for whatever reason. I still make use of the lock feature itself and will probably seek an alternative next season. I recommend this as it's affordable and I'm assuming my alarm issue isn't a widespread problem. October 24, 2013
exelelent alarm This disc lock is awesome it looks great. Easy to install easy to use in my bike. The alarm sound very loud it sound even if you shake ur bike October 22, 2013

Sharon W: Needed a lock for my bike. Jan 15, 2014
Rhett V: I chose this because I do not have a garage to lock my dr650se in. I also commute to areas in Honolulu where motorcycle theft is very common. This lock is extremely solid and the alarm feature adds a to the security of your bike. Dec 1, 2013
Allison H: Audible alarm. Nov 15, 2013
Rolando A: to protect my motorcycle Sep 28, 2013
Jose R: good product and best price. it was recommended by a friend. Sep 19, 2013
Michael G: Best alarm-lock made that will fit on my rear disk, in my opinion. Would have loved to use the XX-14, but that model with the larger bolt will not go through the vent holes in my rear disk. I think it's most important to have the alarm on the rear, where it's harder to defeat. I use a conventional (non-alarmed) lock on the front. Got this one in the bright yellow color. Aug 27, 2013
Adam F: It had awesome reviews and I needed it for where I worked in a downtown area. Aug 23, 2013
Timothy D: It was the best option for theft/vandalism deterrent. Aug 19, 2013
Randolph B: First try at a disk lock with alarm. Your video reviews very helpful. I think with the alarm it will keep me from trying to drive off without taking off lock first (like I did with other non-alarm models). Aug 19, 2013
Ernesto G: rated well, easy to use and carry Aug 18, 2013
A shopper asked: Does vibrations or louder exhausts from other motorcycles set off the alarm? Apr 28, 2011

Sundance99: 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. Jul 18, 2012

Jduh: Nope, I live close to a highway and to vibrations did it yet. Also, I park it kind of close to the garbage bins, and it never went off when the garbage truck came. There is also a bump a few feet away from where I park my bike, and many cars "jump" over it, and that didn't set it off either. Jul 29, 2011

Chris K: I have a Xena system on my bike and it has not gone off unless the bike was actually moved. There is a combination of vibration sensors and a gyroscope that determine the alarm function, so it usually is pretty foolproof. Apr 28, 2011

Austin A: I had my brothers zx10r right next to my bike with this lock on and he really let it rip and it did not go off. The alarm is more physically sensitive than anything else Oct 2, 2013
Reply to Austin Good answer? Yes (0) No (0)
TDevil7: No, the bike must be physically moved. If the axis of the lock changes the alarm goes off, so vibrations from cars or exhaust will not set off a false alarm. Feb 5, 2012

justin s: I had to throw this out after having it for about three months. Apparently ants like to get inside and nest. Once they took hold of it the unit would randomly go off and eventually stopped working all together. I would not order it again. Mar 29, 2014

Hao D asked: Does the locking pin on the XX6 fit through the vent holes on a 2nd generation Ninja 250R? Sep 9, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Ashton E: 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.

Dennis N: I wish I knew. I ride a 2009 BMW K1300S and the locking pin on the XX6 fits perfectly through the vent holes on my bike. By the way, the lock is great! It is highly visible which deters would-be thieves, it is easy to use, and definite triggers an ear-piercing sound when activated. Sep 18, 2013

Hao D: Confirmed. It will fit on a Ninja 250R 2008+ but the entire brake disc will be in the throat of the lock. It will NOT fit in the vent holes. Sep 19, 2013

Ernesto G: I have a BMW g650gs and it fits fine. But I find it easier to go thru the larger gaps in the disc. This lock will reach! Sep 18, 2013

A shopper asked: 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? Feb 10, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Patrick K: 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

I didn't check to see if RevZilla carries replacements.

A shopper asked: 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,

Sundance99: 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. Jul 18, 2012
Reply to Sundance99 Good answer? Yes (1) No (0)
RevZilla: You will need to measure the distance from the outside diameter of the brake disc to the inner diameter of brake disc. Once you have that measurement you will be able to verify it to the lock you are interested in. The lockS we offer usually are accompanied with a schematic showing the distance between the locking pin and inside of the lock that goes over the disc. For example, the Xena XX-6 will fit over a disc brake that is not more than 42 mm (outer to inner diameters). Jul 18, 2012

Shifties: If you're going to get an Xena, the XX-6 is the smallest one. And the one most likely to fit your bike. The larger ones may not fit. Sep 24, 2012
