Sai : What Kind Of Saiyans Have Faster Reflexes Than An Average Human?

Speed and agility saiyans possess tremendous levels of superhuman speed, easily capable of breaking the sound barrier, even with their basic moves. they also have much faster reflexes than an average human; reflexes so fast that they can avoid a bullet without any trouble at all, or even catch them with no harm. their superhuman speed can easily be seen in their fighting skills; their movements occur in fractions of seconds which are not visible to average human eyes, and even "super" humans, like krillin, tien or yamcha, have trouble following up a saiyan's speed.
