Abstract: A front fender of a motorcycle, particularly a dual purpose vehicle serving as both an ordinary motorcycle and a moto-crosser, securely connected to front forks supporting a front wheel at lower ends. The front fender includes a front section and a rear section each arcuate in shape. The two sections of the front fender are telescopically fitted one in the other so that the rear section can be moved into and out of the front section in sliding movement. The two sections can be secured to each other by securing means so that the length of the rear section projecting rearwardly of the front forks can be adjusted as desired to suit the condition in which the motorcycle is used.
