Piaggio scooter secondary transmission 16/47 with Polini bearings

Secondary transmission PIAGGIO Z=16-47 Ø17.7 with bearings, models 1999->

The transmission ratios extend the final ratio of the motorcycle. If the engine has enough power and can handle a longer transmission ratio, the top speed increases.

The original cylinder in most cases does not have enough power, so it will need to be replaced with a more powerful one.

If you are not sure which is the ideal transmission for your setup, please contact us.
