YASUNI Weights - 29 mm, 21.5 g (14 PCS)
This spare part is intended for the YASUNI variator; these weights (rollers) allow you to maintain or adjust the primary transmission of your urban scooter. Designed to replace worn elements of the variator drum, they help restore a consistent engine behaviour and a controlled rev-up, suitable for urban use.
These weights fit directly into the YASUNI variator roller and allow you to adjust the inertia of the rollers to modify the acceleration response and the operating rev range. Ideal for urban riders looking for reliable tuning and simple maintenance of the transmission. Installation and balancing according to manufacturer recommendations are advised.
