Castrol’s full synthetic motorcycle oils come from science rather than nature. They are chemically engineered in our labs to meet the incredible demands of today’s high performance, high temperature engines.
Crucially, they combine high protection with low viscosity, to deliver instant throttle response and pulse-quickening acceleration. These are our most advanced chemical formulations, liquid engineered to flow fast and minimize friction.
