Claim:
1. A motorcycle comprising a frame, two front steering wheels, a steering pipe rotatably connected to the frame and rigidly connected to two supporting assemblies, one for each front steering wheel, each supporting assembly being constrained by fixed portions or rods of two telescopic elements, and a steering group comprising two pairs of transversal arms—upper front, lower front, upper rear and lower rear—arranged inverted at the opposite sides of a central steering pipe and laterally connected through two lateral posts, wherein each pair of telescopic elements is cantilever-mounted to its corresponding steering wheel, sliding portions or legs of each pair of telescopic elements being constrained to each other and arranged parallel to each other so as to make both telescopic elements of each pair lie on a plane parallel to the plane of the relative steering wheel, each telescopic element being internally provided with an elastic element and an oscillation damping element in order to provide the motorcycle suspension, said constraint between the sliding portions of the telescopic elements hindering the relative rotation of said sliding portions around their own axis in order to control the steering angle of each wheel with respect to the frame depending on the rotation imparted to the central steering pipe, wherein said steering group further comprises a control rod screwed onto a steering axle, in turn inserted inside said central steering pipe and wherein on the control rod there rests an inner ring of a ball bearing, and wherein the outer ring of said ball bearing is inserted in a transmission element connected to a steering bar.
