Why You Should Wash Your Motorcycle Engine

Mud or dirt clogs an engine’s cooling system, which is cooled by air circulation in two-stroke and some four-stroke engines. When dirt, oil, and mud stick to the outside of the engine, it becomes difficult for air to cool the engine. The only remaining cooling element in these cases is lubricating oil, but it may not be sufficient.

Engines that are cooled by an antifreeze liquid have ducts between the radiator and the engine. This helps to make the liquid hotter so it can chill in the air.

In this case, dirt and mud don’t allow air to flow freely between the radiator channels, so the antifreeze liquid doesn’t cool down; therefore, the motorcycle’s engine remains hot.

The antifreeze hoses and lines of the motorcycle are exposed to dust. The dirt dries them out and can break them, leaving the motorcycle without a coolant system. It will need many repairs to fix.
