The 2-stroke engine requires 2 strokes to complete the power cycle and on the contrary 4-stroke engine requires 4 strokes to finish the power cycle. As a fact, 2-stroke engines comprise high power to weight ratio. With the small cycle of power generation, they deliver high speeds instantly.

2-stroke engine

On comparison with the 4-stroke engines, 2-stroke engines are lighter and compact. Due to lesser moving parts, they are highly efficient and give better performance while driving. Moreover, 2-stroke engines require less maintenance than 4-stroke engines.
