This part being universal, it may require adaptations
Replacement or precise adjustment of the variator: these YASUNI weights are designed to equip the primary transmissions of urban scooters and mopeds fitted with a compatible YASUNI variator. Compact and robust, they allow for a consistent transmission behaviour after wear.
These rollers (weights) are intended for the YASUNI variator and are aimed at urban riders concerned about a reliable adjustment of their transmission. Ideal for replacing worn rollers or for testing a different variator setting, they allow for adjusting the engine behaviour in terms of revving and acceleration response according to the chosen weight. Simple installation, to be checked with the manufacturer's documentation for model compatibility and timing.
Workshop advice: before any intervention, check the wear of the tracks and the variator drum, change the rollers in pairs if necessary, and respect the recommended tightening torque to ensure safe and durable operation.
