Motorcycles are provided which include 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 and a steering group consisting of two pairs of transversal arms&#x2014;upper front, lower front, upper rear and lower rear&#x2014;arranged inverted at the opposite sides of a central steering pipe and laterally connected through two lateral posts. On each of the supporting assemblies the fixed portions of two telescopic elements may be constrained. Each pair of telescopic elements may be cantilever-mounted with respect to the steering wheel.

Tiltable motorcycles with two front steering wheels

A motorcycle suspension comprising a fork having a steering bar suitable for connecting mechanically to a steering mechanism of a motorcycle, an oscillating bar having a first end at which it forms a junction with said steering bar, and a second end at which it connects to a support which houses a rotation pin of an associable wheel so as to turn, said rotation pin defining a rotation axis for the wheel itself. The suspension comprises a shock absorber unit which extends from an attachment head, at which it is mechanically connected to the steering bar, to an attachment foot, at which it is connected to the support. Advantageously, the shock absorber unit, at the attachment foot, connects to the support by the interposition of mechanical coupling means having a hinge axis which is contained in a plane perpendicular to the rotation axis of the wheel.
