Secondary transmission Piaggio scooter <98 14/48 17.7mm Polini

Gear ratios extend the final drive ratio of the motorcycle.
If the engine has enough power and can handle a longer gear 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, contact us.
NOTE! The inside of the gear is smooth! For installation, you must use a press!

Can only be installed on Piaggio models manufactured from 1999 onwards!
