DOPPLER secondary transmission is not complete without axle shaft or primary gear, so take the original transmission parts and fit them to the press. This transmission is ideal to start anew and gain top speed on large configurations, indeed, it often happens to the limits of the scooter (inverter and torque control closed and open bottom, engine at its bottom). .. Thanks to the extended transmission, you will get more top speed at the same engine speed, usually a gain of 10 to 15km / h from 10,000 to 13,500 laps! This transmission is only mounted on MINARELLI VERTICAL motors (list below). The teeth, unlike the origin is right, it's a little noisier but also more powerful! Less power loss!
