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!

I have bought loads of different oils in the past to try and get the best for the bike and I never really trust the reviews fully, but I stumbled across this oil and briefly looked at the reviews and the price so I give it a try. I am glad I did ask this oil really is the best on the market at this price and with SBS price match if you can find it cheaper in the UK and I doubt that very much and coupled with the FREE next day delivery. All I have to say is excellent product from an amazing and also excellent company with service and its customers at it's heart.
