Description Secondary Transmission Polini 14/48 incl. wheel shaft with buffers Piaggio after 1998The transmission ratio of the gearbox has a major impact on engine performance. The gear ratio is changed it can keep up with the surplus power of a tuned engine and transmit this power into tangible results, be it in terms of top speed or acceleration. A taller gear favors top speed at the expense of acceleration.This is a special edition from Polini, a secondary transmission teeth = 14 / 48 that comes with a shock-absorbed wheel shaft. This reduces load shift effects and vibrations. The output shaft was lengthened to allow the installation of the Polini Torsen WD swingarm.Note: Changing the gear on the intermediate shaft requires a hydraulic press or a corresponding assembly tool.

Notes and Safety Scooter gearboxThe 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!
