150kms avec 5mn de pause à mi-trajet, aucune surfauffe à déplorer, excellent rapport qualité prix, même la culasse bipartie est magnifique et la consommation est franchement raisonnable, à peine plus qu'un 50cc vu le couple incroyable pour un 85cc. Une segmentation entre 3000kms et 5000kms me semble être raisonnable en fonction de comment il a été traité
Personnellement je ferais un piston aux 10000kms lors de ma deuxième segmentation et vous tiendrais au courant de l'état de celui ci
Tourne à la Castrol XR 77 2%, rien à signaler
