Elongated primary transmission 13/43 DOPPLER horizontal minarelli scooter (nitro, aerox, ovetto ...)

Ideal to gain top speed with a good congiguration, here is the extended primary transmission DOPPLER for 50cc scooter MBK, YAMAHA, APRILIA ... HORIZONTAL MINARELLI engine like nitro, ovetto, sr ...! 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 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 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, no need for press, the first pinion in 14 teeth is delivered to you already mounted to the press!
