Customer Reviews for Mammoth Original Disc Lock

Mammoth Original Disc Lock
July 26, 2019

Quick, additional deterrent

I chose the 10mm pin as my disc brake will take it. It is fitted in seconds - slide it on and push pin down to lock. I squirted a bit of WD40 (as tipped by another customer) which made the pin release a little more easily. The plastic weather cap fell off after 2 days of use but the carry pouch helps to avoid dirty smudges when pocketed after release. Good value for money as a quick, extra deterrent. Also have a chunky chain lock for more substantial security.

Strong little detterent

Brought this for my new 125cc bike and will be using it with my chain lock . May not be very strong to stand any stealing attempt but will be good deterrent. I use it a handy little lock when I go for quick shopping

Neat but a little fiddly

Benefit of the doubt 4*, this thing is quite nice and compact (6mm),and I like the plastic weather cap. On mine the lock is a bit fiddly to get it to release though, but perhaps that's a knack thing. Comes with a little canvas pouch with a belt loop/small strap combination so you could attach it to the bike somewhere, but the velcro fastener isn't mega secure.

Mammoth disc lock

The mammoth disc lock is simple to use and does what it's supposed to. It isn't fancy with alarms or anything but a simple solid well made lock that is fairly priced. It comes with a handy carry bag so all in all I am satisfied with it and have no complaints

Good Disc Lock

Good solid lock for the money. Handy to carry in the jacket pocket or top box. Bright colour and comes with it's own little pouch to keep it in. Paired mine with a slinky type lock reminder to avoid trying to ride off without removing the lock.

Great

Does what it says on the tin. Delivery was fast as always from Sportsbikeshop. Excellent deterrent for the price, like other reviews cap is a bit flimsy but I'm extra careful and haven't lost mine yet even tho it's popped of a couple times lol.

  • hi can you tell me whitch size do I need for Yamaha wrx125cc thanks

    February 13, 2018

    As the product is a universal fitment, we do not have any information on specific bike fitments. The 10mm pin will be stronger and harder to cut/break.

  • Hi will this fit Yamaha wrx 125cc

    February 12, 2018

    As the product is a universal fitment, we do not have any information on specific bike fitments. However, we can see no reason why it should not fit.

  • Hi SBS, Can I just ask what the actual depth of the Jaw is on the larger 10mm Mammoth lock is, as it looks quite long and I need 6.7cm to clear the Disc from the back of the Jaw to the start of the pin on our Honda.

    September 26, 2017

    The depth of the jaw measures 6.2cm on the larger disc lock.
