Abstract
A snowmobile includes a chassis comprising a bulkhead and a tunnel, a front suspension coupled to bulkhead, a rear suspension coupled to the tunnel, and slide rails coupled to the rear suspension. The rear suspension includes a toggle link pivotally coupled to the tunnel at a first pivot coupling, and a rear control arm coupled between the slide rails and the toggle link. The toggle link is pivotally coupled to the rear control arm at a second pivot coupling. The rear suspension also includes a carrier roller coupled to the toggle link. The toggle link is movable to a plurality of positions relative to the toggle link to vary the dynamics of the vehicle propulsion.
