Sensitive, but not quite loud enough.
13 May 2024 by Anonymous
Just about fits through the discs on my g310gs, wouldn't go any bigger.

As others have said though the alarm could be louder and it is a little too sensitive - it goes off too easily when I'm trying to unlock it.

Great product, feels sturdy, and loud enough for most needs
Good lock but alarm a bit quiet
05 April 2024 by John D
Seems well made and easy to use but the alarm is a bit quiet when outside. Not sure how many passers by would pay it any attention. Like how easy it is to lock it without the alarm activated just by placing the hasp in the other way round.
Strong and quality feel.

Quality, Robust lock that works well. Alarm sensitive, loud and effective. Excellent value, great price from sportsbikeshop too.
Solid but definitely not loud
26 March 2024 by Evan
Super strong and sturdy lock. The alarm itself is switchable i.e. it's not always on, you've got the option to secure the lock without the alarm.

The alarm itself though is pretty weak. Not sure where the 100db comes from.
Visible, audible deterrent
26 March 2024 by Martin S
Appears high quality and tough. Great visible deterrent, the large size and bright colour helps with this. This also gives it a downside in that it's heavy and a bit awkward to carry. Overall though it's a great product and I'm very pleased with it.
Solid replacement lock
19 March 2024 by Steven F
This is a replacement as my old one (over 12 years) is not so sensitive and pretty battered now.
The new lock is very sensitive and is very solid. I use it with an Oxford chain.
A great lock.
Secure in france
18 March 2024 by Clive P
Just bought this ready for a trip to France on the GS. A very robust all be it heavy unit. The alarm is good & seems loud enough, it is quite sensitive but certainly won't flap around in the wind due to its weight. I am happy with it thus far.
Good lock but pathetic alarm
18 March 2024 by Brian L
The lock itself appears to be robust and well maid. It's easy to use provided you have the right space and angle to I stall it on the front disc. However, the volume and duration of the alarm is pathetic to say the least. It needs to be twice as long in duration a d about 5 times louder. Not impressed.
Good lock, very sensitive.
06 March 2024 by Phil S
Big enough to see, feels like it could deter the scallies but luckily not had that tested while using. Alarm is not as loud as some other Oxford locks but is annoying when going off. Sets itself when locked in the correct position (red to red tabs on the shackle) Would have given 5* but gave 4* due to low decibel sound from the lock. Good price and service from SBS as usual.
Solid but cumbersome
13 February 2024 by Rich
I use this as a disc lock but I got it because I thought I could use it with a chain if needed. It is solid, but it's a little awkward to get the shackle through the back of the disc when there are 2 of them. The alarm could be louder but it still makes a decent racket and detects the bike being moved with no false alarms. so far.
Oxford boss disc lock

This a good, inexpensive disc lock with the added bonus of also being an alarm. My only gripe would be that it isn't very loud when it goes off in my garage, so I can barely hear it when I'm indoors. Outdoors, however, it is plenty loud enough and a sufficient deterrent to warn off opportunistic thieves

Boss Alarm

I quote " does what it says on the tin" could be a bit louder , would be happier to pay a couple a ££ more to include a reminder tag ( bendy wire thing ), but otherwise very good product

Questions and Answers

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, 2019

    To 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, 2018

    The alarm is not supplied with a reminder cable.

  • How long is the chain?

    November 30, 2017

    No 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, 2017

    We 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, 2017

    The 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, 2017

    The 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, 2011

    The 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
