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.

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.

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.

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!

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).

Better air filter

Decided to fit a K&N filter to the Bonneville and could not believe the difference it made. Improvement throughout the rev range and better throttle response. Excellent service from sportsbikeshop.

Upgrade

My Thruxton EFI was always a little jerky on the throttle at low revs, it is now so much smoother and the engine just breathes better. Feels like a restriction has been removed. Great product, excellent service.
