Here is what a bike sprockets would look like and conversion change ..
now here is a differential in a car ..
when people talk about drivetrain hp loss they are comparing to fwd cars and rwd cars etc .. there is no diff in a GSXR so there is no drivetrain loss. That graph is apples to oranges and the physics is different. I thought this was common sense to you but maybe you didn't know that about motorcycles.
