Function and Use
The rollers convert rotation into centrifugal force to control the opening of the variator. Their mass determines the shift RPM: lighter rollers promote a higher RPM, while heavier rollers lower the RPM. This set of 9.5 g allows for adjusting the variator's response for a consistent acceleration and responsiveness in line with original or tuned settings.
Why Choose Malossi
Malossi is recognized among motorcyclists for its performance-oriented and reliable parts. These rollers are suitable for routine maintenance or fine-tuning of the variator on most CVT scooters. Always replace rollers with a complete set to ensure balanced operation of the pulley.
