  • Patent number: 7131507
    Abstract: The invention relates to a tracked ATV which is fully supported, driven and steered by a pair of parallel endless tracks driven by means of an internal combustion engine. Steering means are arranged to control the differential speed between the tracks for steering the vehicle. A handlebar is pivotally mounted to a vehicle body in front of a driver seat and the steering means are arranged to be operated by rotation of the handlebar. According to another aspect of the invention the driver seat is a straddle-type seat and footrests are arranged on the body to the left and to the right of this seat, which footrests are situated vertically in between an upper run and a ground engaging lower run of the tracks.
