Ideal for gaining top speed with good congiguration, here is the POLINI elongated primary transmission for scooter 125cc 4T with PIAGGIO engine ...
Like ZIP, LIBERTY, BEVERLY, VESPA ... (list below)! Often, with a large kit, we arrive at peak speed limit because we arrive at the limit of the engine speed once the drive and the torque control are at 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 revs from 8,500 to 11,500 rpm! Do not forget to order the transmission oil that goes with it! This transmission in straight teeth is a little noisier, but also more powerful! The right set of teeth offers less loss than the original (helical) leaning!
