Tougher that I imagined

Essentially this lock is an Oxford Nemesis with an added case for the alarm system. The Oxford Nemesis is one of the strongest locks in the market, so I assume this will perform just as well. The difference is that this one is yellow and is alarmed, so thieves will think it twice before they attack it. A minor detail that would have been nice is if the shackle was coated with rubber so that it does not scratch the bike. I have added it to mine using a heat shrinking tube. But for the price it has, this is a great option.

Very compact and sensitive to movement I'm happy without. The only think I can't tell you is weather it can withstand a theft attempt, but it is a definite deterrent and looks very compact...

Great price from SPORTSBIKESHOP!

I bought the 14mm version of the Oxford Boss alarmed disc lock. Certainly up to the job it's supposed to do I'd say. I would have given 4 stars except I do find locking and unlocking a bit fiddly and the lock should also include a minder cable.

Really good portable security

Needed something more portable than a chain, this ticks all the boxes. Lightweight, high visibility, alarmed.

Portable and sturdy

Alarm works as it should, although be careful not to move it just after locking up. It's quite easy to carry around in a backpack, and will alert a large radius if it was to go off either in town or late night at home.

Not very loud.

The lock itself seems good, but the alarm could do with being abit louder and it only sounds for 10 seconds then resets itself.

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
