A tie down system for a two wheeled vehicle includes a support plate providing a wheel chock for receiving the front wheel of the vehicle and a pair of diverging arms extending away from the wheel chock. An adjustable strut connects between the ends of the diverging arms and the frame of the vehicle rearwardly of the pivot connection between the front wheel and the frame. Once adjusted, the struts act like solid links resisting any forces applied by the vehicle when it is being towed. Suitable locks may connect the struts and the vehicle frame providing a measure of security.
