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.

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.

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!

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).

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.

I reccomend....

Completes Knox body armour.

Looks & feels good inside Knox body armour protection top. Obviously don't want to do a 'full test' of protection but it's a lot cheaper (I managed for £100) against the airbag type vests. Might need Knox under vest a size larger to accommodate.

Good and a bit thick

What it says on the tin, feels the part and for the money no grumbles you will need plenty of room in your suit as it's a thick thing.

Very good fit and perfect compliment to back protector. Added bonus is that it definitely helps a lot to keep your chest warm in colder weather, when you might normally need to wear extra base layers.
