Only use with tuning kits! Original cylinders are normally not powerful enough to pull this sort of gearing. For all Piaggio engines built since '99 with counter bearing in the gear cover. Transmission ratio: 16/37 Questions about the product

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!
