There is often confusion when it comes to identification of J2 and J2X types because they are seemingly very similar. However, the most obvious differences are that the J2 nose does not extend past the front tyres and has two vents below the grille, while the J2X nose has a more protruding chin with a single vent below the grilles. In standard form, the spare wheel was carried hidden on top of the rear-mounted fuel tank, but either version could carry one or two side-mounted spares. This allowed the use of a 40 gallon long distance fuel tank.
