Description
Polini is one of the big names in 50cc scooter tuning, and is also one of the leading manufacturers of tuning parts for Vespa, modern and vintage. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your Vespa.
This Polini Primary Transmission with straight teeth for 4-stroke Piaggio / Vespa 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.
- Gear ratio: 15/49 (3.27)
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!
