Description Polini High Speed Variator for SYM Jolie / Red Devil / Jet4R / Jet Basix. The variator is the automatic gearing system in a scooter – it relies on finely tuned weights that operate via centripetal force to smoothly and seamlessly increase the gearing ratio. A performance variator changes the way your scooter changes its gearing ratio, for optimum efficiency, smoothness and in many cases additional top speed.
