Boss alarmed disc lock
25 February 2025 by Anonymous
I use this lock as part of a layered security system. The alarm is quite sensitive to vibration and obviously gives you an audible warning that someone is around your bike. I wouldn't use this as a single theft deterrence. The Litlok X3 gives far better security against angle grinder attacks if I was only able to use/carry one device but as I say a sturdy secondary audible deterrent and is listed on insurance comparison sites as well.

Oxford Boss Disk Lock - Visual Deterrent
28 January 2025 by Richard M
Good and hefty disk lock, seems very robust! It is not the smallest device but is very noticeable which gives a good visual deterrent.
Not the loudest but 100db is loud enough to warn off a would be thief

Having owned this lock for just over a year it malfunctioned, I contacted SBS and they without hesitation exchanged it for a new one. AMAZING CUSTOMER SERVICE as always x love this lock too, it's very loud when tampered with and great for putting my chain through

Sturdy lock

This lock is very strong and well made. I would think it would slow would-be thieves down. One downside, as others have said, the alarm is not particularly loud!

I've used the oxford alarm disc locks on my motorcycles for many years without issue. Very secure, well put together, easy to use, visible deterrent. Would have given 5 stars but they don't include a minder cable anymore. Highly recommend!

Chunky, heavy, but not ear piercing

Great lock that I'm sure would take time to break or remove. Long in shape so fits around wheel brake disc easily. Could be a bit louder in my opinion.

Boss Alarm
09 October 2024 by Anonymous
Pretty easy to use, although I had to find a youtube video to figure out how it works as instructions are not great. It's very straightforward though.
It's pretty massive for a disc lock, and bright yellow so quite a visible deterrent
My only problem is that the alarm isn't that loud, there's no way I'd hear it from inside my house without windows open.
It's not overly sensitive which is nice. Trying to move the bike will set it off but unless you're very heavy handed you won't trigger it by unlocking it or taking a cover off or something.

Great Purchase

A substantial lock from Oxford that fits through the front disc of my motorcycle. .
Easy to set up in either alarmed or none alarmed state. Alarm is quite loud and whilst it's not going to stop the scraps stealing your pride and joy at least it goes some way to alert you that someone is tinkering with it.
Another great purchase from SBS.

Like the physical size of the lock and quality.The presence of the lock when fitted certainly stands out as a deterrent although it's not as loud as I thought it would be.That said it fits under the seat of my Vstrom so all in all very pleased with it

It's huge!
13 July 2024 by J B
I purchased this lock as its sold secure and recognised as a high security lock by my insurer. The lock is very big and heavy with a half moon shaped key way. It's coupled with a chain and the bike is secured to a ground anchor. It can also be used as a disc lock but the shackle is very thick and won't fit all discs. The alarm is not very loud but should help to deter opportunistic thieves. All in all, I'm pleased with my purchase and would recommend the Oxford boss lock.

Great lock
15 June 2024 by Andrew B
I like how this is versatile and can be used with a chain or disc. Easy to use but the key could be a little tricky for some as it has a half circle design and can only be inserted into the lock in one way.

Questions and Answers
Is the alarm set separately from the locking mechanism? I'm just thinking about when its stored in a top box when travelling.
April 28, 2019To de-activate the alarm, insert the shackle into the lock so that the red band is not next to the arrow on the case.
Does the Alarm include a minder cable?
May 22, 2018The alarm is not supplied with a reminder cable.
How long is the chain?
November 30, 2017No chain is included,you will receive a lock only.
I'm going to be buying a NC750x will this disc lock fit this bike at all?
November 22, 2017We are not able to advise on fitments to specific bikes, but the measurements of the 16mm shackle are 41mm width and the length (depth) is 53mm. These are the internal measurements of the shackle.
The hole in my disc is 6 mm. Will this fit in the holes?
March 5, 2017The Oxford Boss Alarmed Disc Lock is available in 14mm and 16mm shackle sizes, and so the shackle would not fit the holes in your disc.
Is this the Oxford Big Boss Alarm. Part no.OF4?
February 13, 2017The 14mm shackle is Oxford part number OF3,and the 16mm shackle is is OF4.
Could you please tell me what the batteries are and are they easy to remove?
July 27, 2011The battery type is LR44 1.5V and replacement procedure is fully covered by the comprehensive instructions. Spare batteries are available to purchase at Sportsbikeshop.(See link below) https://www.sportsbikeshop.co.uk/motorcycle_parts/content_prod/62749
