Fantastic price for a solid bit of kit. Very easy to use although it doesn't come with any visual reminder like other models do.

Chunky monkey

Solid bit of kit and on my insurer's list of approved disk locks (though not convinced they gave me much of a reduction in premium, but that's insurance companies for you...). It's big, solid and fairly heavy - you're probably not going to want to carry this around in a pocket. One gripe is that the key needs to be fully inserted up to the hilt - a couple of times I've been unable to do this very easily, as the key has hit an obstruction on the way in and it's taken several minutes (my record is over 4 minutes) of wiggling and wrestling to persuade it to go in. I'm keeping it lubed with silicone 'oil' and hoping it improves - may have to return for a replacement (hopefully) if it doesn't.

Robust disc lock

Looks and feels very strong, a little chunky so it's not pocket friendly. Overall very pleased, lock cover is a little tricky to open with gloves on. I would recommend this product to anyone.

Reassurance when parking

I bought this for my new KTM Duke, which incredibly for this day and age has no immobiliser or even Datatag fitted! Needing quick, easy to carry but substantial protection, I selected the Oxford Monster in yellow (to make it obvious to both thieves and me). It feels very solid and hence provides some reassurance that the bike may still be where I left it. Hopefully. It's very easy to use and fits under the Duke seat.

Great bit of kit

Big & Beefy

Serious bit of kit this. Feels quality and has a rubbery body to protect your bike against scuffs etc Comes with 3 keys and a rubber keyring. When unlocked the whole lock shaft is removed and placed through the brake disk then re-inserted into the lock body and secured with the key. Gives a great sense of security when the bike is out of site.

    The Oxford Monster Disc Lock has a shackle width of 11mm. The distance between the underside of the shackle (U shaped piece)and the top of the lock is approximately 70mm. You will need to measure the fitting area on your disc in order to check that the lock will fit.
