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).

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!

Click & Collect

If you can't be around to receive your delivery during the day, just use one of our simple click & collect options. We offer delivery to a shop local to you using both the UPS Access Point network and 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.

55,000+ Reviews

Whilst we know a bit about bikes and bike kit, the best road testers out there are our customers, real bikers, just like you. If you're looking for advice on what to buy, you'll find over 55,000 independent product reviews which we've posted, unedited, for all to see. Whether it's a question about sizing, quality or something else, our customer reviews are quite simply, the best place to start.

365 Day Returns

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.

Great Value

Seems a strong sturdy lock. Park in London so need all the locks I can get. This fits through the sprocket easily with just enough space to bolt up over the chain/sprocket combo. Not overly weighty so it wont be painful carrying in a backpack or topbox.. too big for a pocket though (weight wise). Nice touch with the lock hole cover

Solid lock

Good strong lock. Portable and easily clips under my seat. However, the key can get stuck occasionally and require a fair bit of fiddling to get it to unlock.

The Dogs Bo**ocks . . .

Bought for a Harley Tourer as a visual deterrent to back up the factory alarm system. Large shackle makes it easy to manoeuvre the lock into position. Supplied with four keys. Good, solid lock with smooth locking mechanism,at a competitive price. You can pay a hell of a lot more for a disc lock that won't do much more than this. Highly recommended.

Disappointed, doesnt even fit around my disc

Got a Honda CB125F and this disc lock doesn't fit it. Also there is limited space in between in to get two bits of a chain link in.

Not up to scratch

Bought this as a gift for my son but was disappointed that the lock was faulty and would not open at all. Returned and replaced immediately by shop but replacement just as bad. Must be a faulty batch as see other reviews are good. Am returning for a refund. Service from shop absolutely faultless though. Would give them 5 stars without doubt.

Good value, seems strong

This is decent value. It seems strong and sturdy. I chose this as it is one of the few disc locks that will fit my older Ducatis. I don't know how it will stand up to a sledgehammer, hopefully I'll never find out! It's a good visual deterrent though. As usual service from Sportsbikeshop was superb. Delivered in 48hrs. Cracking price.

Highly visible and great value

Not the heaviest disc lock of this type that I've come across. This one looks more substantial than it probably is, making it a great visual deterrent and meaning there's no excuse not to carry it and use it. However, it's very cheap compared to alternatives which makes it a great value supplement to other security devices I use.

Good bit of kit

Brilliant bit of kit, has the bright yellow to say 'oi thieves better back off m8' and looks and feels like the bike is secure! As much as I love this brands security I wished they changed the colour of the keys. I have one of their lock and chain and it's the same colour so it's always the luck of the draw when choosing which key would fit. Pretty happy with the product! Bikes not been stolen so it must be doing something!

Bigger than it looks

Could be too big to fit within the rim of some wheels. Good aspect of this lock is that it can be also be used as a padlock with a chain.

Seems sturdy enough

Bought this disk lock for my Honda CB500X (2016). It seems very sturdy and I like the color. It only fits the front disk. Would be great if I could put it on the back wheel as well.

Good lock

I wanted something bigger than a disc lock, but still portable. This lock may be too heavy to fit comfortably in my jacket pocket but good for under the seat or tank bag.

Solid and reliable

This is a great disc lock. Solid weight in it and well made. Fits in my jacket pocket as well so handy for getting around town. Would recommend.

Surprisingly good lock

A surprisingly heavy, sturdy lock. Ideal for the front brake disc on most bikes.

Decent little lock

This lock is bigger then others out there which means its a bit to big to go in your pocket but it acts as more of a deterrent as it looks more sturdy and great for the price. Feel confident leaving the bike during the day with this lock on.

Handy bit of kit

Good lock, would fit on most disc brakes. Bought it to take with me on long trips instead of taking my big chain. Only negative point is that it doesn't come with a reminder cord, these are essential, it would be so easy to forget it's there. You can pick up a cord anywhere though, for a few quid.

Perfect

Although fortunately I can't say how well this lock stands up to a thief I would imagine it would hold them back for a while as it is fairly tough and pretty thick. It also comes with 4 keys which is handy.

Heavy but secure

It's not bad, I know it needs to be heavy but it is not the most portable.
