Elongated primary transmission 14/39 POLINI for scooter PIAGGIO DIESIS, ZIP 50 from 2000

Ideal to gain top speed with a good congiguration, here is the POLINI elongated primary transmission for scooter 50cc PIAGGIO 50cc. Often, with a large configuration, we arrive at peak speed limit because we arrive at the limit of the engine speed once the drive and the torque controller are at the bottom, 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 from 11 000 to 13 5000 revolutions per minute! Do not forget to order the transmission oil that goes with it! This gear in right gear is a little noisier, but also more powerful! The right set of teeth offers less loss than the original (helical) leaning!

Less than the 16/37 we offer too!
