Synthesis XRP is one of Rock Oils flagship lubricants, formulated and developed in conjunction with Rock Oils superbike support programme. This ground breaking oil has been developed from cutting edge synthetic base stocks and a bespoke additive technology enabling more nett engine power to be released from your machine, dyno tests have seen increases of up to 5 percent! Another real benefit from this new technology are engines that run cooler in race conditions.

When Rock Oil launched Synthesis XRP a decade ago, it was a serious step forward in lubrication for both race and road motorcycles. It offers superb protection and increases the performance of the vast majority of motorcycles.

With most bikes pushing out very high levels of horsepower per litre as standard it can be very hard to verify any gains such is the out of the box performance on most bikes. Some users claim they can feel through a crisper throttle response or a smoother gear change. Its only when you put a motorcycle on a Dynamometer that true improvements can be measured. Although launched 10 years ago Synthesis XRP has been updated a number of times and today is still providing the very best performance possible for 4 stroke motorcycles.

Rock Oil's Hong Kong importer Sanwa Motorcycles decided to put the claims to the test and run some of their own independent dyno tests to assess the performance of the oil on a modern, large capacity road bike. Both Sanwa and Rock were delighted to see a peak horsepower gain of 4BHP on the BMW S1000 RR they had selected for the test. With BMW currently being one of the more desirable sports bikes, it was especially gratifying to see such a gain on a bike such as this especially as it had only 2000km on the clock. Running the standard oil it managed a figure of 175.6 BHP and with XRP the peak figure was 179.5 BHP which represents a serious gain and as the dynometer operator stated a massive improvement for something which could be part of a standard service interval.

Synthesis XRP is the engine oil of choice for Rock's sponsored road teams and teams such as Buildbase BMW (who themselves are running a race version of the bike tested) and Gearlink Kawasaki will be running it in their race engines this season.
