A snowmobile includes a pivotally mounted motor cover that moves between open and closed positions relative to the snowmobile's frame. A latch fastener selectively secures the motor cover in its closed position. The latch fastener includes a pin that is rigidly mounted to the frame and positioned such that the pin extends through an opening in the motor cover when the motor cover is in the closed position. A resilient latch mounts to the frame and selectively engages the pin to hold the motor cover in the closed position. When the motor cover is in the closed position, the pin engages the peripheral edge of the opening to discourage the motor cover from moving relative to the frame. The latch covers the tip of the pin to discourage clothing, debris, etc. from catching on the pin.
