Having a Wet Clutch actually means that the clutch and plates are immersed in oil, the same motor oil as your engine, they actually share it, the oil flows through the engine and clutch, lubricating, cooling & cleaning as it goes both internal engine and clutch components a like. Motorbike oils that are suited to "wet clutches" have special additive packages within them to cope with the extra strain of operating in this manner, plus they have friction modifiers to prevent clutch slip, if you were to add the same grade car oil you'd find it almost impossible to ride without your clutch constantly slipping.
Our oils have been hand picked by the Opie Experts, we only stock oils we trust and would be happy to run in our own bikes, so you can buy with confidence
