POLINI Roller Set 20x17mm 10 g - 9 pieces
The POLINI rollers are designed for riders who want to finely tune the behavior of their variator transmission. Each roller, calibrated at 10 grams, allows for modifying the gear ratio by influencing the engine's RPM and response, without guaranteeing any specific unverified gains. Ideal for scooters and machines equipped with roller variators, this set facilitates precise tuning down to a tenth of a gram to find the desired compromise between acceleration and top speed.
Installation as a replacement or for tuning tests: remember to replace all the rollers with a homogeneous set to avoid vibrations and uneven wear. Check the condition of the variator tracks and retaining clips during the change. A simple yet essential piece of equipment for anyone fine-tuning their transmission with precision.
