The POLINI rollers Ø25x19 mm are designed for urban riders who want to fine-tune their variator settings. This set of 9 rollers, each weighing 16 g, allows for precise adjustments to the CVT transmission by varying the mass of the rollers, in order to achieve the desired engine behavior in the city: quicker accelerations or smoother revs depending on the chosen setting.
This kit is suitable for variators that accept rollers of these dimensions. POLINI rollers are made with materials and a finish suitable for daily use in urban environments. For safe installation and optimal adjustment, check the condition of the variator's groove and ramps, and adhere to the specifications of your scooter's manufacturer. If necessary, consult a professional for installation and adjustment.
