Looking at the CGI model, the robot torso and crotchplate are actually similar in size between cheetor and Tigatron. I think Cheetor's fake beast head is an engineering work around to allow the real head behind it to be remolded as a larger, tiger head. The limbs on Tigatron are where most of his mass come in, along with his head.
