Secondary transmission 15 / 54 elongated POLINI for scooter APRILIA SXR 50 4T from 2021

Ideal for gaining peak speed with good configuration, here is the elongated secondary transmission POLINI for scooter 50cc APRILIA SXR 4T 2021, 2022, 2023, 2024, 2025... Euro 5 standards. Often, with a large configuration, you arrive at the peak speed limit because you arrive at the limit of the engine speed once the dimmer and torque adjuster are deep, so the solution is to put an extended transmission. Thanks to this transmission, your speed will be higher at the same engine speed! We usually win 10 to 20km/h in diets of 11,000 to 135,000 laps per minute! Do not forget to order the transmission oil that goes with it! This transmission comes with its bearings so that it can be placed on needle sockets! Thus increase the longevity and performance of the scooter by reducing forcing. This transmission is in straight teeth (noiser than the helical) to reduce friction and increase performance.
