The amount of drag an object is subjected to comes from two things; the frontal area of the Motorbike and what’s called its drag co-efficient. The frontal area of motor cycle involves head lamp, petrol tank, front mud guard, front panel in case of mopeds. The greater the frontal area will increase the resistance to drag and hence the power is lost in overcoming this air resistance. Therefore, the shape of head lamp , shape of petrol tank position and shape of mud guard which reduce the frontal area will improve the performance reducing air resistance called air drag.
