contact pattern so it creates more gear noise nternal ear ratio is the physical number derived by dividing two gears by themselves ective ear ratio is the overall outcome of a gear with an effector for example with a primary sprocket change the overall output of the transmission will be affected by the primary gearing change overall ear ratio is the primary ratio x internal ratio x final drive ratio this value is what harley-davidson uses as standard measure.
