What is dirt bike engine?
Dirt bike engines are designed for high performance at the expense of some longevity. The clearances between all the moving parts - which themselves are made of different alloys, and different shapes and sizes, all with different and very critical rates of expansion when hot and contraction when cooling - are kept within limits by the cooling effects of air, oil, coolant and the fuel itself, plus the lubrication from oil and fuel.
