This part being universal, it may require adaptations
YASUNI weights designed for variator: replacement rollers intended for CVT transmissions of scooters. These weights allow for adjusting the variator's response for an engine behaviour suited to urban driving, by influencing the acceleration curve and the engine speed without promising unverified numerical gains.
Replacing the rollers with a homogeneous set avoids vibrations and uneven wear of the belt. These weights are aimed at riders who want to refine the scooter's response — better acceleration in the city, more responsive starts, or consistent engine speed — while remaining within the settings compatible with the YASUNI variator. For optimal results, check the condition of the movable pulley, rails, and belt during installation.
Manufacturer reference: CDIT7369 — original YASUNI spare part for maintenance and adjustment of the transmission.
