A method and system for assembling a vehicle of a family of vehicles includes providing a group of engines. A first engine including a first number of cylinders corresponds to a first vehicle. A second engine including a second number of cylinders corresponds to a second vehicle. The second number is greater than the first number which is at least one. A cylinder plane extends vertically and longitudinally. At least one cylinder is disposed at least partly forward of a front wheel plane. The transmission assembly is rearward of the selected engine and one of the transmission assembly and the selected engine is in a same location whether the selected engine is the first or the second. The seat is at least in part longitudinally rearward of the transmission assembly. The selected engine is laterally disposed between the centers of the footrests.
