I am no racer so guys who have done track-days shall be in a better position to answer your query.

Thanks for your reply bro. By listening to MotoGP commentators somehow I know how riders pull off some super human maneuvers. Brakes are used to transfer the weight distribution but the riders use their body position to balance the bike in high lean angles.

The frictional force equals the product of coefficient of friction and the normal reaction. Under hardbraking the coefficient of friction remains the same, so only way to increase fricional force is to increase the normal reaction which equals the force exerted by the front tyre on the ground. When the braking is done as in tap in method the weight transfer is too quick and there isn't enough friction to prevent lock up. On the other hand when we slowly(not so slowly) increases the brake pressure the normal reaction increases making more contact patch and better friction. So its more effective than sudden application of brakes.
In hard braking often the rear brakes will be making little contact with the ground. And if we are braking with only front brake, the rear wheel still has the inertia that will increase the stopping distance . So we need to slow them as well to follow our intended line. But as in panic situation the effect of not using rear brake is not so critical.
