In a single cylinder engine, merely one power stroke for every two revolution of crankshaft, Whereas in multi cylinder engine the power stroke is given by number of cylinders.
So that in Single cylinder engine there is more rotational energy required which is given by heavier flywheel. In multi cylinder engines the energy not required that much and each cylinder gives power. so, it has lighter flywheel.
