Description
Doppler Primary Transmission 15/50 - 13 CPI / Keeway. Taller gears reduce the overall gear ratio of your transmission and will result in improved acceleration, a higher gear ratio increases top end speed. Stock engines usually don't have enough power to pull this kind of transmission, so you will need a sports or racing cylinder.
Get rid of your old gear, grab this Doppler transmission, mount it and give'r!
- primary transmission: 15/50
- pre-pressed for use with original secondary gear with 13 dents
Scooter gearbox
The transmission of scooters and some mopeds is located in a case behind the clutch and torque driver and has the function of reducing rpm and ultimately driving the wheel axle.
The transmission of a scooter has a direct influence on top speed. If the engine develops enough power and torque at low rpm, you can choose a longer gear ratio to achieve a higher top speed without any noticeable loss in acceleration.
Please note: if you don't have a press, better choose pre-assembled gears!
