POLINI Roller Set 19 x 13.5 mm - 12.5 g (6 pieces) · Manufacturer Ref: 242.160
This POLINI roller set is aimed at motorcyclists and scooter riders who want to fine-tune the behavior of their CVT transmission. Delivered in a pack of 6, each roller has a diameter of 19 mm, a width of 13.5 mm, and a precise individual weight of 12.5 g, suitable for variators designed for these specifications.
The rollers allow for fine calibration of the variator: by changing the weight, you adjust how the engine revs and the response to kickdown. This kit is suitable for replacing worn rollers and restoring consistent behavior of the pulley. For optimal installation, check the condition of the variator groove, the belt, and the sides before reassembly.
Workshop advice: always replace all 6 rollers simultaneously and check compatibility with your variator model. This POLINI set is a simple and reliable solution for those looking to adjust inertia and fine-tune the transmission.
