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.

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.

Awesome plug

Much harder to stall a bike, more torque, slightly better acceleration and huge improvement in throttle response! Thank you.

Better performance, longer lasting

Title says it all. For the extra few pound per plug, I'd definitely recommend the iridium.

Good upgrade

I changed from a regular plug to the Iridium ones and the one thing I noticed was morning cold starts in the minus temps was very smooth and got rid of some jerky riding experiences for the first 2-3 mins.

Good buy

Fixed an issue on my bike where the old spark plug was rusted and water was getting into the engine. This fixed that issue and although I can't tell much difference because I'm on a 125, I'd definitely recommend this.

Changed from OEM plugs and these are an instant improvement, bike seems smoother and has better throttle response from the off. Great service and fast delivery, will definitely be buying from them again.

Great spark plug

Great spark plug indeed. First time I've changed for an Iridium one but I can feel the difference. The bike starts a lot nicer and just feels more responsive and smoother.

Bought and received spark plugs for my bike. Unfortunately, I ordered the wrong type and Sportsbikeshop exchanged them no problem and no fuss. I will buy all my products from them.
