YASUNI Axial 4T Variator: a variator designed for urban scooters, it incorporates YASUNI's exclusive patented axial transmission technology. This system optimises the management of the gear ratio for a more responsive throttle and a smoother riding experience, particularly in urban environments and during mid-range accelerations.
The YASUNI Axial 4T variator is aimed at scooter riders looking for a reliable and responsive transmission without altering their machine. It fits many urban models (e.g. Piaggio Liberty 125 IE) and is suitable for daily commutes as well as frequent starts in the city. Manufactured and distributed by YASUNI, it meets manufacturer standards to provide a high-performance alternative to the original variator. For optimal implementation, follow the manufacturer's recommendations and have the installation carried out by a professional if necessary.
