An experimental motorcycle that uses opposite sense 2 Wheel steering. I.e. The rear wheel steers in the opposite direction to the front. The 'Steering Ratio' or degree of rear steer to front steer is adjustable. The video shows a slalom test that was conducted at various increments of steering ratio. The test proved that a significant improvement in times around slaloms with sharp corners can be achieved with 2-wheel-steering. Other findings were that a high and forward centre of gravity is desirable (hence the seating position) and that a rear-to-front steering ratio of around 0.6 gave the best times and the best compromise between improved manoeuvrability and reduced stability. The bike was designed, built and tested as part of a mechanical engineering degree dissertation by James G P Jones (of South Shropshire, UK) at the University of Wolverhampton in Feb 2011. The disseration also includes the control theory associated with the balance and stability of 2WS as well as explanations for the improved manoeuvrability.
