le 04/05/23, équipés d’une transmission TX-8. Il est possible qu’un dispositif de verrouillage n’ait pas été installé
sur les pièces de fixation du collet d’assemblage de la fourche de l’arbre de transmission. Ceci pourrait permettre

pendant la conduite et/ou une défectuosité des pièces de fixation augmentant le risque d’accident.
Quel est le problème ?

Il est possible qu’un dispositif de verrouillage n’ait pas été installé sur les pièces de
fixation du collet de l’arbre de transmission, occasionnant un desserrement des pièces
de fixation.

transmissions et appliqueront un dispositif de verrouillage,
