Set of MALOSSI rollers designed to precisely control the variator of your scooter. This kit of 8 rollers, manufacturer reference 6613561.A0, is made from CPT according to a specific formula signed by MALOSSI — a robust solution for the maintenance and adjustment of the transmission.
Why rollers matter
Rollers govern the engagement of the variator through centrifugal effect: as they rotate, their mass generates a push that alters the travel of the movable pulley and thus the gear ratio. The weight directly influences the RPM at which the variator engages: heavier rollers cause the ratio to engage earlier, while lighter rollers delay this engagement.
Usage and advice
This 12 g kit is aimed at riders looking to adjust engine response and RPM range according to their style — either more responsive at acceleration or more relaxed in the torque zone. Replace worn rollers to restore precise variator behavior and avoid vibrations and slipping. Installation is recommended by a qualified workshop if necessary.
