Abstract
A snowmobile includes a chassis having a generally reduced length and a snow flap pivotally attached to the rear portion of the chassis, above the track system. The track system extends rearwardly beyond the chassis, and the snow flap shields the track system above and behind from spraying snow. The snow flap is linked to the track system so that as the track system moves through a range of travel relative to the chassis, the snow flap pivots relative to the chassis with the track system. This configuration prevents damaging contact between the tread and the undersurface of the snow flap and/or the chassis. The reduced length of the chassis decreases the weight of the snowmobile and the polar moment of inertia, thereby improving turning performance. A bumper extends from the snow flap and can be used to lift the rear of the snowmobile more easily.
