A commoner's interest in bikes is limited to keeping themselves updated regarding the latest model of bikes launched, their engine capacity, or the power rating. Seldom will you find people with comprehensive knowledge about how power gets generated or what technologies are used to ensure the smooth running of bikes.
The cooling system of the engine in a bike keeps it working on its most efficient temperatures. Cooling is vital for all engines to operate and function properly. Cooling is important, especially in hot climates as high temperatures tend to damage engine materials and lubricants. Hence, it would not be incorrect to say that the lifespan of an engine, and its survival, rests on its cooling system.

The cooling tech for a bike has three categories, based on the cooling method deployed viz.
1. Air-cooled engines are the most commonly used technology, present in the majority of Indian bikes. They use air as the cooling agent for engine cooling. They have fins around the engine cylinder that facilitate cooling by exposing the increased surface area to air for bringing the temperature down.
2. Oil-cooled Engines help maintain the viscosity and lubrication of the oil through an optimal operating temperature. To do this, the oil is circulated between an oil cooler and is cooled by the flowing air, that, in turn, cools down the engine oil. This cooled engine oil is rolled back via another jacket.
3. Liquid-cooled Engines are used by all high capacity bikes in India as well as abroad. It ensures stable performance even in crowded traffic conditions, on uphills, and during high-speed riding. In this system, there is a web of passages around the cylinder that circulates the coolant, which, in turn, keeps the engine temperature cool and under control.
In a nutshell, from the above discussion, it is obvious that the air-cooled engines are quite primitive and inefficient as compared to the oil and liquid-cooled options. This technology is mainly used for almost all commuter bikes.
The oil-cooled engines come with an added cooling mechanism and are definitely better than the air-cooled versions, for commuter bikes. However, even they are not suitable for high performance.
The best option for racer and dirt bikes, which require high-performance and speed, is the liquid-cooled engines. Although they work out to be a little heavy on the pocket, their efficiency and environmental friendliness make them extremely popular and most sought after; like the Dominar 400 vs the Duke 390, both of which use liquid-cooled engines.
Whatever cooling technology your engine bike may be using, you need to ensure three things most importantly:
