Description
This Polini Primary Transmission 16/51 Yamaha 50cc 4-stroke 3V with helical teeth for 4-stroke Minarelli engines will change the gear ratio of your transmission so the surplus power of a tuned engine can be adequately handled and transmitted, be it in terms of top speed of acceleration. The quality of the gears is, as per usual with Polini, outstanding - precisely machined and very robust.
Change of gear ratio in most cases involves changing the variator weights as well to avoid losing torque / acceleration. And please do not forget to change the gear oil.
- gear ratio: 16/51
- primary gear
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!
