POLINI elongated secondary transmission 16/47 for APRILIA SR scooter, PIAGGIO NRG, TYPHOON, VESPA, GILERA RUNNER 50 ...

Ideal for gaining top speed with good configuration, here is the POLINI elongated secondary transmission for 50cc scooter PIAGGIO, GILERA ... Often, with a large configuration, we arrive at the top speed limit because we arrive at the speed limit motor once the variator and the torque corrector are fully down, the solution is therefore to put an elongated transmission.

Thanks to this transmission, your speed will be higher at the same engine speed! We generally gain 10 to 20km / h in speeds of 11,000 to 13,500 revolutions per minute! Don't 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 sleeves! Thus increasing the longevity and performance of the scooter by reducing the forcing. This transmission is in straight teeth (noisier than the helical) in order to reduce friction and increase performance.
