POLINI Roller Set 20x17mm 10 g - 9 pieces
The POLINI rollers are designed for riders who want to finely tune the behaviour of their variator transmission. Each roller, calibrated at 10 grams, allows for modification of the transmission ratio by affecting the rev-up speed and engine response, without promising unverified precise gains. Ideal for scooters and machines equipped with roller variators, this set facilitates tuning to within a tenth of a gram to find the desired compromise between acceleration and top speed.
Installation as a replacement or for tuning trials: remember to replace all 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.
