Abstract

La présente invention concerne un véhicule (100) à deux roues avec un ensemble cadre (F) où un ensemble moteur (112) est monté sur l'ensemble cadre et configuré dans un espace (S) formé par l'ensemble cadre (F) au niveau d'une partie d'extrémité du ou des bras. L'ensemble moteur (112) est placé sous un amortisseur arrière (108) et en avant d'un pivot (114) de bras oscillant. Le présent montage maintient la rigidité, la durabilité du véhicule (100) et aide à maintenir le centre de gravité, l'accessibilité, la facilité de montage et de démontage, et l'aptitude à l'entretien, tout en facilitant le refroidissement de l'ensemble moteur (112).
