  • Patent number: 7240758
    Abstract: An all terrain vehicle (“ATV”) is disclosed having a frame with front, rear, right, and left sides. An engine and at least two wheel axes are disposed on the frame. A plurality of wheels are disposed on the at least two wheel axes. The engine includes a cylinder disposed adjacent a crankshaft and a generator operatively connected to the crankshaft. An output shaft, separate from the crankshaft, operatively connects to the engine to transmit power from the engine to at least one of the plurality of wheels through at least one of the wheel axes. The output shaft is disposed between the cylinder and the generator in a plane substantially perpendicular to at least one of the wheel axes.

  • Patent number: 6896087
    Abstract: An all terrain vehicle (“ATV”) is disclosed having a frame with front, rear, right, and left sides. The frame defines a frame centerline extending longitudinally between the front and the rear sides. The ATV includes an engine with at least one cylinder having an axis that defines an engine centerline. The all terrain vehicle also includes an output shaft defining an output shaft centerline. A continuously variable transmission (“CVT”) operatively connects the engine to the output shaft and defines a CVT centerline. The engine centerline, output shaft centerline, and CVT centerline are positioned with respect to one another and the frame centerline. In one embodiment, the engine centerline is disposed between the output shaft centerline and the CVT centerline. In this embodiment, the engine centerline also may lie between the frame centerline and the CVT centerline.
