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.

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.

60,000+ 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 60,000 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.

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.

Free UK Delivery

Great product

Really good quality sprockets, significant weight saving over OEM sprockets and hard anodised so will last for ages. Excellent customer service from sportsbikeshop when I ordered the wrong size originally but they exchanged no problems!

Went on a GSXR 600 K3. Loads lighter than the stock steel and looks better. Went on as a set with new gold DID chain and 1 down Renthal front sprocket.

Excellent to the point it becomes boring ordering from Sportsbikeshop. The only way it can go wrong is when the post man gets drunk.

  • Ultimate combination of strength and lightness
  • Enhanced 7075 T651 aluminium alloy
  • Hard anodised coating
  • 33% lighter than steel sprockets

NOTE The second half of the part number above refers to the pitch

Renthal hard anodised sprockets are specifically designed for road and road racing applications. They feature all the benefits of Renthal off-road aluminium rear sprockets but with increased longevity from the hard anodised process. Hard anodising is an integral surface coating which significantly increases the hardness and wear resistance of the chainwheel surface.

Renthal hard anodised rear sprockets are precision CNC manufactured to extremely high tolerances. The high strength is especially enhanced by using a 7075 T6 aluminium alloy coated in an ultra hardwearing finish for extreme mileage. The rear sprockets computer aided 'Ultra light' design gives the maximum reduction of unsprung weight at the rear wheel, to give maximum power transfer. The Renthal rear sprockets are 33% lighter than steel and the self-cleaning mud grooves prevent dirt build up and help keep the sprocket clean.
