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!

60,000+ 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 60,000 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.

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.

15+ Years Online

We've been serving the motorcycle community for more than 15 years now and in that time we've grown to be the largest online retailer of motorcycle clothing & accessories in the UK.

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

I have bought loads of different oils in the past to try and get the best for the bike and I never really trust the reviews fully, but I stumbled across this oil and briefly looked at the reviews and the price so I give it a try. I am glad I did ask this oil really is the best on the market at this price and with SBS price match if you can find it cheaper in the UK and I doubt that very much and coupled with the FREE next day delivery. All I have to say is excellent product from an amazing and also excellent company with service and its customers at it's heart.

High quality oil

Suzuki don't recommend fully synthetic oils in my model so I use Comp 4. I have had no issues in the last 3 years, so no reason to change. SBS is also the most reliable supplier, it's the one to go to.

Liquid gold with gold standard service

I was put onto this oil from my Triumph dealer and it's great in my Speed Triple R. Other reviews are all positive too. The icing on the cake is the super service from these guys too, arrived quickly with no drama.

Good service

I needed some oil for my Honda urgently and was unable to travel. My oil was delivered the next day. As for its quality and performance, then time alone will tell, but I am very impressed with service.

Like wine in a box

Very easy to order, very fast delivery, came in cardboard box, like wine in a box, if you want the plastic container then this is not for you. Old oil was poured back into the box and then taken to the tip, no mess.
