Reduced to its common reasons for being essential in an internal combustion engine, cooling system efficiency can have a dramatic influence on the longevity of the internal working components of your bike's engine. These include the reduction of thermal stresses and strains caused by pre-ignition and detonation (particularly the latter), distorted cylinder bores, potential damage to pistons and rings, and damaged valve-train components.
