Oxford Boss Alarmed Disc Lock

Solid lock

Solid, chunky, weighty lock with loud alarm. You don't have much time to unlock it but that's ok for me - the less tamper time for thieves the better. Would be nice to have a minder cable included but I got one off amazon for a few £. Overall v. Happy with product.

Reliable and does the job!

I bought this for my Tiger 800, and it works as it needs to. It fits through the front brake disc perfectly, and the bright color automatically attracts your attention to it. I have my bike parked on the side of the road, and haven't suffered any false alarms with it, but the alarm does go off if i turn my wheel, or try move the lock in anyway. The alarm isn't piercing loud. but it is quite loud, enough to attract the attention of everyone in my street or in a parking lot during the day when its busy - which for the price is worth it.The lock itself is pretty solid and feels very heavy duty. It isn't quite as compact as a Xena 14 / 15, so it doesn't fit under my seat on my bike, and can be a bit clunky if its in your pocket, but that's OK for me as I have a top box to put it in when travelling. This lock does exactly what i bought it for.

Has a good strong feel about it, can be a little fiddly trying locate the key into position but not to bad, only thing preventing me from giving it a 5 star was the 100db just does not sound load enough

It certainly is BOSS!!

The Oxford Boss Alarmed Disc lock is almost a necessity for me in this hobby! Like all locks they're a deterrent to slow down thieves but not only does this one slow them down, it screams at 100db to scare em off too and alert anyone nearby. That is because it has a motion thingymajig that when its put in alarm mode, and it's moved, it'll ring. It's sturdy as hell, and it feels like a hardy product. Like I said, a necessity!

Does what it says in the tin (kind of)

It's a good lock with a loudish alarm, however the lock isn't big enough to go through both the wheel and disk of a KTM super duke gt. You end up just "hanging" it off the disk. It's still a visual deterrent though which is the main purpose.

Sturdy. Great lock!

Lock very visible and loud! Should have been a remember cable included but that's not a deal breaker for me as I have some lying around.

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) http://www.sportsbikeshop.co.uk/motorcycle_parts/content_prod/62749
