RAVENOL Racing 4-T Motobike SAE 10W-40 is a fully synthetic 4-stroke motorcycle engine oil that was specially developed for racing use with USVO® & CleanSynto® technology. It is designed 100% on a PAO and ester basis and can therefore also be classified as “fully synthetic” according to German law. Thanks to a special formulation based on the new RAVENOL racing technology, we achieve a perfect combination for the engine, transmission and clutch. The excellent properties of the fully synthetic PAO base oils and esters ensure maximum performance and reliable protection against wear.
