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.

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.

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. You can choose from any UPS Access point close to you where you can drop off your return at a time convenient for you.

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.

200+ Top Brands

There simply isn't a better selection of biking brands anywhere in the UK and we're constantly updating every range to ensure you have the best choice available.

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!

Good looking, functional product

Looks good on bike, easy to clean too. Hex nut makes for easy removal and prevents overtightning. Pretty inexpensive too so couldn't ask for more.

K&N303 R1 2000

A tight fit to get on behind the headers without loosening them, just took a bit of wiggling. Good fit and considerably heavier than the filter that was on, because I had heard that some K & N filters used to split when tightening them up, no problems with this one at all.

K&N is good kit

When is an oil filter, more than an oil filter? When it's a K&N filter. Ok, so maybe that's bit of a stretch, but what can you say about an oil filter really? I like this filter because of the brand, K&N are renowned and because of the nut on top which makes it hella easy to fit and remove. This website offers them cheaper than anywhere else I have found.

The nut on the end makes life easy. No need to struggle with a strap or chain wrench in a tight spot

Easy fit for clean oil

The KN-303 filter has not presented any oil flow issues and oil remains clear between changes. The hex head makes the filter easy to fit and, with a ring spanner, you can remove it without scalding your fingers! As ever, Sports bike shop is quick, efficient and excellent value.

K&N at there best

Perfect fit, nice addition of the hex on top of the filter to aid fitment/removal over a standard filter. Used K&N in the past on my cars and always found them good.

I use these due to them having a bit on the end which makes removal and installation easier. Good quality and value as expected from a brand like K&N and SBS.

Quality service

Never had any issues with K&N oil filters. Nut on the end makes removal easy. Quick delivery and great prices from SBS.
