Final drive ratio
In Turkish: Son aktarma oranı
In short
The final drive ratio is the rear sprocket tooth count divided by the front sprocket tooth count; it sets how engine power is geared to the wheel.
For example, a 14-tooth front and 42-tooth rear sprocket give 42 ÷ 14 = 3.00. A higher ratio (bigger rear or smaller front sprocket) gives livelier acceleration but less speed at the same rpm; a lower ratio drops cruising rpm.
The overall ratio to the wheel = primary ratio × gear ratio × final drive ratio. See the effect of a change in percent with our gear ratio calculator.
