After years of development work Rock Oil have developed Synthesis XRP Gearbox- a fully synthetic motorcycle gearbox oil which has been race-developed to give extra power. This development, inconjunction with extensive field-tests has resulted in a real breakthrough in performance with demonstrable enhancement in power coupled with increased wear protection. Whilst the formulation was originally designed to produce more nett engine power it has been found that gear units run cooler than with a conventional lubricant. The advanced combination of additives combined with the purest synthetic base stocks significantly reduces wear and keeps all gear components clean. Features Outstanding thermal and shear stability Superb wear protection Significantly reduces friction, thus reducing power loss and improving gear changes Passes crucial clutch friction test required to meet the JASO MA and MA2 specification, allowing safe, predictable performance in wet clutch applications Synthesis XRP Gearbox meets or exceeds the following specifications: API GL-1 API SL JASO MA / MA2
