Abstract
A snowmobile includes a pair of skis connected to the snowmobile frame by a forward suspension including a pair of telescopic struts which are biased to normally extended positions and are connected to a stabilizer member including a transverse torsion bar. A drive track of the snowmobile is suspended from the frame by a rear suspension, including a link pivotally connected between the frame, and a pair of slide rails and biased downwardly by a pair of torsion springs having respective ends engaged with a pivotally mounted spring end retainer which is connected to the torsion bar of the forward suspension by a pair of motion transfer links which act to 'soften' the rear suspension in response to upward telescopic movement of one or the other or both of the telescopic struts.
