Fantastic product

I normally use the cheaper brand oils but thought I would use Castrol as it was priced very good. Glad I did because I won't use anything else now.

Quality

Have been using Castrol lubricants in my Triumph because it is recommended by manufacturer. Quality product and performance of motorcycle maintained. May change to fully synthetic for the next oil change as engine has loosened up nicely. Highly recommended.

Total satisfaction

Extremely good service, prompt and packaged well. Cheapest price I could find too. I was given an unregistered Spyder Scooter to sell after owner did not want it. Still waiting to sell it. Not tried it, myself but it fired up fine. Thank you.

Outstanding service and delivery

I have used Power 1 4T for several years and have always found that it does a good job for my Sanya. (Chinese copy of Suzuki EN125) The engine runs smoothly with reduced friction and this has helped promote longevity in a motorbike that seldom reaches the mileage that I have completed on it. This was the first time that I used Sportsbikeshop and I initially ordered the wrong oil. (My fault not theirs). I contacted them by email to advise of the problem and their response was far beyond the level of customer service that I expected. Not only did they arrange for the return of the mis-ordered oil but both the original delivery and the delivery of the replacement oil were super fast. Personally for the service and the price I will not be using anyone else for my oil purchases. OUTSTANDING SERVICE AND DELIVERY. Try them - I'll be surprised if you are not absolutely delighted.

Reliable oil

Just bought a new Bandit 1250 and wanted the right oil. After some research and advice from direct from Suzuki I went for this Castrol. Good price from SBS and great service. Thank you.

Never use cheap oil again

Brilliant product, bike seems to run quieter. Revs freer and pulls better after a change to this. I'll always be using Power 1 from now on.
