After years of development work Rock Oil have developed Synthesis XRP Gearbox- a synthetic motorcycle gearbox oil which has been race-developed to give extra power. This development, in conjunction 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.
