Air-Cooling Vs. Oil-Cooling Vs. Liquid-Cooling

Biking enthusiasts worldwide enjoy the thrill of riding; owning a bike involves understanding crucial components like the cooling system. In vehicles with internal combustion engines, including motorcycles, the cooling system prevents overheating caused by explosions and friction. Ignoring overheating signs can lead to engine damage.

Types Of Cooling Systems

Although automakers have experimented with a variety of heat-control techniques, three primary engine types—oil-cooled, liquid-cooled, and air-cooled—have become increasingly common.

  1. Air-Cooled Engines

Common in Indian bikes, air-cooled engines use fins on the engine, allowing air to flow through and cool it while in motion.


  • Simple production and maintenance
  • Cost-effective


  • Ineffective for high-performance
  • May result in engine seizure

Examples: Hero Xtreme 160R, TVS Apache RTR 160, Royal Enfield Bullet 350, Suzuki Gixxer, and Yamaha FZS-FI.

  1. Oil-Cooled Engines

Oil-cooled engines share the cooling fin concept with air-cooled ones but include an externally mounted oil cooler. The engine oil is cooled by air flowing through the oil cooler.


  • Superior efficiency compared to air-cooling
  • Basic technology with reasonable maintenance


  • Not suitable for fast bikes
  • Can increase vehicle weight

Examples: Royal Enfield Continental GT 650, TVS Apache RTR 160 4V, and Royal Enfield Interceptor 650.

  1. Liquid-Cooled Engines

Liquid-cooled engines commonly use a coolant circulated through internal channels in high-capacity motors. The coolant absorbs heat from the engine and is then cooled in a radiator by air and fans.


  • Extremely effective for cooling engines
  • Sustains performance at high speeds for extended periods


  • Expensive and intricate manufacturing
  • Costly upkeep

Examples: KTM Duke and RC models, Yamaha R15 v3, Bajaj Dominar 400, Honda CBR250R.

The purpose of the bike will choose which engine type to use: liquid, oil, or air. Although they are less efficient and use antiquated technology, air-cooled engines are nonetheless quite affordable. Although oil-cooled engines have an extra cooling mechanism, they are less appropriate for high-performance vehicles than liquid-cooled engines, which operate well during lengthy, fast drives.

The distinction between liquid-cooled and air-cooled engines is less significant for commuter bikes, as stress on the engine is minimal. However, for high-performance vehicles like racer bikes and dirt bikes, liquid-cooled engines are the preferred choice.
