POLINI Roller Set 20x17 mm – 14.7 g (6 pieces) - Manufacturer reference 242.166
The Polini rollers 20x17 mm weighing 14.7 g are designed for scooters and machines equipped with CVT transmission. Packaged in sets of 6, they provide a simple and reliable solution for fine-tuning your secondary transmission: changing low-end behavior, modulating gear engagement, and adapting engine characteristics for urban or highway use.
Designed within the tolerances suitable for modern variators, these rollers are easy to install during a transmission service. Check compatibility with your model before installation (dimensions and number of rollers). Replacing or testing different roller weights remains a proven method for adjusting acceleration behavior and engine operating range without altering the main mechanics.
POLINI product, a reference for riders who want to fine-tune their transmission with confidence.
