Secondary Gears Polini 14/48 Piaggio NRG after 1998

Description A longer transmission will get the power where your need it and increase your top speed, always under the condition that your engine is powerful enough to begin with. This means you should definitely use this transmission with tuning cylinders only, as original cylinders are simply not powerful enough. Gear ratio: 14/48 (3,43) => +7% Shaft diameter = 17.7mm 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!
