Secondary transmission 14/48 lengthened POLINI for scooter DERBI, PIAGGIO DIESIS, APRILIA SCARABEO, ZIP, VESPA 50 4T ...

Ideal to gain top speed with a good congiguration, here is the POLINI elongated secondary transmission for 50cc scooter PIAGGIO, GILERA, DERBI, VESPA 2T and 4T ... Often, with a big configuration, we arrive at the top speed limit because we reach the limit of the engine speed once the drive and the torque controller are at the bottom, the solution is therefore to put an elongated transmission. Thanks to this transmission, your speed will be higher at the same engine speed! We usually win 10 to 20km / h in diets from 11 000 to 13 5000 revolutions per minute! Do not forget to order the transmission oil that goes with it! This transmission is delivered with its bearings to be able to put it on needle sockets! Thus increase the longevity and performance of the scooter by reducing the forcing. This transmission is in straight teeth (noisier than helocoidal) to reduce friction and increase performance.
