On cars that have them they are air cooled since there is no radiator.
cooling fins are used to cool down the engine by having the cool air pass through the fins which gets transferred down to the engine, so on a motorbike like all other engine's the cooling fins cool down the engine.
those fins are equivalent to the radiator grill on a car they allow air to be blown out by fans to assist in cooling the engines
Emit blue haze from the exhaust, engine sounds busy, large engine cooling fins, no valve gear in cylinder head.
cooling
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
Cleaning, cooling, lubricating
yes if the dust has stuck to radiator,and blocked the cooling fins, it will sure enuff cause over heating. with engine off, you can usually wash dust and other debri out of radiator fins from the engine side, using a hose.do not use a pressure washer as this will damage the fins

Aluminum or copper.
They are called "cooling fins". Motorbikes use air-cooled engines, and the "fins" distribute the heat over a great deal of surface area so the air can carry off the heat more efficiently.
