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!

SBS dependable as ever.

Specifically recommended for my bike but not easy to find. SBS always have it at a good price and I had it within 48 hours of ordering.

Superb service as usual

The product speaks for itself, service by Sportsbikeshop was the usual, prompt and efficient with the item well packaged. Why would you shop anywhere else?

Bema service

This is the first service I have done on my BMWr1200gs and was not sure about what type of engine oil to use but after some research found this is OK. Done the service and it runs like a dream. SWEET.

Good quality oil for my Aprilia Shiver

Unable to find 15W-50 oil as recommended for my Aprilia Shiver. I was glad to see it was easily available on Sportsbikeshop.
