          Notes de version du micrologiciel

          Mis à jour : 12 août 2026

          2020+ Cypher III

          2020+ SR/F & SR/S + 2022-25 SR + 2023+ DSR/X + 2024+ S & DS & DSR

          MBB V46, BMU V22, BMS V28

          Nouvelles fonctionnalités :

          • L'état de santé de la batterie de chaque module est désormais accessible via les outils de diagnostic du concessionnaire.

          Corrections de bugs / Améliorations :

          • Correction : Un défaut a été corrigé qui pouvait, dans certaines conditions, permettre aux motos équipées d'un Power Tank de démarrer en étant alimentées uniquement par le Power Tank avant que la batterie de traction principale ne soit détectée. Cela pouvait entraîner une réduction de l'autonomie et une perte de puissance potentielle. Remarque : Après cette mise à jour, la moto attend que la batterie de traction principale soit détectée avant de pouvoir rouler. Sur les motos équipées d'un Power Tank, un léger délai à la mise sous tension peut se produire dans de rares cas. La recharge n'est pas affectée.
          • Correction : Un bug a été corrigé qui pouvait entraîner une augmentation inattendue du niveau de charge (SoC) affiché vers la fin d'une décharge, ce qui amenait l'estimation de l'autonomie à afficher une autonomie supérieure à celle réellement disponible.
