No, it is not recommended to use water instead of coolant in a motorcycle cooling system. Coolant, also known as antifreeze, is specifically designed to regulate the engine's temperature and prevent it from overheating. Water alone does not possess the necessary properties to provide adequate cooling and protection for the engine.
Coolants have a higher boiling point and lower freezing point than water, allowing them to effectively dissipate heat and prevent the engine from overheating under
