ABSTRACT:
A front snowmobile suspension of the type having a ski carried at the front end of a trailing arm. The rear end of the trailing arm is pivotably secured to the chassis and the front end of the trailing arm is pivotably secured to the chassis by a pair of generally transversely mounted radius rods which in turn are pivotably secured to the chassis. Each radius rod has an inner end pivotably attached to the chassis and an outer end pivotably attached to the front end of the trailing arm. The outer ends of the radius rods are positioned forwardly of the inner ends of the radius rods a sufficient distance that the radius rods, viewed from the top, form an angle of at least about 15.degree. with respect to a transverse plane that is perpendicular to the chassis centerline.
