Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. … Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable.
Why are 2 stroke engines banned?

Are 2 strokes more maintenance?

Are 2 strokes dangerous?
Two-stroke engines commonly used for gardening and boats can cause serious health problems including cancer, a Griffith University environmental scientist has said.
Why do 4 strokes have more torque?
This is due to the fact that fuel is consumed once every 4 strokes. Four-stroke engines are heavier; they weigh upwards of 50% more than a comparable 2stroke engine. Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM.
Why are two stroke engines more powerful?
A two-stroke engine can theoretically produce twice the amount of power because it fires once every revolution, whereas four-strokes fire once every other revolution. Because of this, it has a higher power-to-weight ratio, making it more desirable for many riders.
What are the disadvantages of two stroke engine?
Disadvantages of two stroke engines
- Two stroke engines do not last as long as four stroke engines; there is no lubrication system in a two stroke engine so parts wear out a lot faster.
- Two stroke oil is expensive; you would burn a gallon every 1000 miles if it were in a car.
- Two stroke engines use more fuel.
