Abstract: A method and apparatus suitable for stabilizing a two-wheeled motorcycle during operation. The apparatus is securable to a location near the front of the motorcycle engine. At least one arm assembly extends in a rearward direction relative to the motorcycle and outboard of the motorcycle's engine and operator's seat. A wheel assembly is mounted at an rearward end of the arm assembly and includes a wheel engageable with a surface supporting the motorcycle.
