Ideal to gain top speed with a good congiguration, here is the extended primary transmission DOPPLER for 50cc scooter MBK, YAMAHA, APRILIA ... VERARIAN MINARELLI engine like booster, spirit, stunt, slider, rocket, next generation ... ( after 1996 only)! 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 therefore to put an elongated transmission. Thanks to this transmission, your speed will be higher at the same engine speed! We generally win 10 to 20km / h in revs of 11 000 to 13 5000 revolutions per minute (two versions with the choices, semi long and long)! 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!
On this version, you need a press, the first gear must be taken from the original transmission and coupled to this transmission!
