Description
Primary gearbox Doppler 15/50-13 CPI / Keeway
From French manufacturer Doppler: Primary gears 15/50-13 (+20%) CPI / Keeway. Taller gears result in a shorter gear ratio, improving your scooter’s acceleration, while a longer ratio favors top speed. Standard engines usually don’t have enough power to handle a changed ratio, so an upgraded ratio is recommended only for tuned engines. Definitely a solid choice if you want to make better use of your tuned engine’s potential.
- Primary gearbox: 15/50
- Pre-pressed, for original 13-tooth secondary shaft
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!
