Free Returns*

We now offer free returns on any UK Mainland order (excluding Highlands) over £25. Most importantly, returning an item to us is super simple. Just click here or on the 'create a return' link located at the bottom of every page, and create your return in under 1 minute.

Award Winning

There's a reason why our competitors spend so much time watching what we do, we believe in customer service levels beyond the norm and we're always looking for ways to improve. In late 2013 we were recognised for this by the bike industry's No.1 publication, Motorcycle News. As retailer of the year, we feel it's our duty to constantly better our offering and if you have any ideas, we'd love to hear from you!

Finance Available

Why wait? We now provide some of the best finance packages around to help spread the cost and get you on the road. We now offer finance on most orders from as little as £280 with 0% packages starting at only £300. The online application process is super simple too and takes around only 5 minutes to complete! The best part is, there's no paperwork to print and in most cases you'll have a decision in under 10 minutes. Just select finance as a payment method and take it from there!

365 Day Returns

We simply don't believe in making the sale and moving on, we want to make sure our customers are happy with their purchase. That's why we now offer a full 365 day returns period. Simply relax, take your time and make sure it's right! All we ask is that you try the items within your own home and return with the tags intact.

Click & Collect

If you can't be around to receive your delivery during the day, just use our click & collect option. We offer delivery to a shop local to you using the DPD Pickup network. Most pick up points are open outside of normal working hours and will keep your package so you can collect at a time to suit you.

Free UK Delivery

It's really simple, if you spend over £25 with us, delivery is free of charge to any mainland UK address (excluding Islands & Highlands).

Happy with the strength

Not easy to put the key in if you are in a hurry due to rotating layers. But it's best for safety.

Quite large

It does what it says on the tin, but the size of the gap was a bit too large for regular brake discs. It's however, mostly a deterrent for joyriders rather than high end thieves as they will take the bike with the lock. So with that in mind, it does it's job as it should.

  • How many keys are provided with this disc lock?

    February 12, 2019

    Two keys are provided with this Disc Lock.

  • 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.
