A wheel suspension system for a motorcycle including a relatively stable member and a swingable member swingably connected with the stable member and supporting thereon a road wheel. The wheel suspension system comprises at least one torsion bar arranged on the stable member, a force transmission route adapted to transmit forces acting thereon, the force transmission route being connected with the swingable member and the torsion bar, and a lever type damper having an operation shaft adapted to provide damping forces when rotated, the operation shaft being engaged with the force transmission route. The system is substantially free from restrictions with respect to configuration and damping force producing direction.
