POLINI Roller Weights 25x17mm 12g - 8 pieces (manufacturer reference: 242.285) — a kit designed for riders seeking precise tuning of their variator transmission. These POLINI rollers offer standard dimensions and uniform weight to allow for tuning within a tenth of a gram.
Ideal for fine-tuning the variator, each roller rolls in the groove to progressively modify the transmission ratio. Replacing a set of worn rollers with new elements allows for smoother rotation and better control of the shift curve on continuously variable transmissions.
With a simple and robust design, these rollers are suitable for most variators requiring these dimensions. For optimal results, check the condition of the variator groove and the rolling surfaces before installation. A complete and homogeneous kit to refine the behavior of the transmission and regain a controlled riding sensation.
