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!

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.

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!

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.

100,000+ Products

Used this filter for a few times already, well made and of course high quality! Easy to remove, because you can use the wrench for it!

Ive been using these for any years now and never had a problem. Much easier to remove/fit than the conventional oil filter. This should be the standard really.

Excellent value for money

Item comes well sealed and packaged to prevent any dirt entering the filter before use. Clean threads and screws onto bike with no issues. Has a hex head on the top for when you do need to remove as well as it having a hole through the centre to allow the securing with a pin if you need to. No discernible performance difference yet but assume it will just be a better flow than an OEM filter when running bike harder than a gentle commute.

Known provenance

Recent practice among oil filter manufacturers is to leave them unbranded in black or sheer colourways, which has the same appearance as fake versions, probably stuffed with newspaper. I have used this K&N before with fully synthetic oil and as I remove my oil filters by piercing with a screwdriver after draining the hot oil, know that it contains filter paper.
