POLINI Roller Set 19x17mm 7.2g - 6 pieces (Manufacturer reference: 242.093)
Designed by POLINI for fine tuning of variator transmissions, these rollers with a diameter of 19 mm and a width of 17 mm provide a reliable solution for adjusting transmission behavior. Sold in packs of 6, each roller has a unit weight of 7.2 g, allowing for precise adjustments to the gear shift regime and engine responsiveness by manipulating the inertia of the centrifugal masses.
Ideal for urban riders and roadster pilots looking to adjust the variator's operating range — acceleration, response, and cruising speed — these rollers allow for tuning to the tenth of a gram when composing your set. Compatible with many 125 cc models and popular scooters (e.g., ITALJET Dragster 125, Vespa GTV 125, Piaggio X-Evo 125), they integrate easily during maintenance or transmission adjustments.
Simple installation and POLINI machining precision: rollers designed to last and facilitate the optimization of your transmission without gimmicks or unverifiable promises.
