Ideal to gain top speed with good congiguration, here is the extended primary transmission DOPPLER for scooter 50cc MBK, YAMAHA, APRILIA ... VERTICAL MINARELLI engine such as booster, spirit, stunt, slider, rocket, next generation ... ( after 1996 only)! Often, with a large configuration, we reach the top speed limit because we arrive at the limit of the engine speed once the variator and the torque corrector are at the bottom, the solution is therefore to put a lengthened 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 appropriate transmission oil! This straight toothed transmission is a little noisier, but also more efficient! The straight teeth offer less loss than the original leaning (helocoidal)!
On this version, no press needed, the first 13-tooth pinion is delivered to you already assembled at the press !
