A cambering vehicle includes a single steerable front wheel and a pair of rear wheels at the rearward ends of trailing arms extending from the front structure. The two arms are articulated to the front structure, and move arcuately in planes parallel to the steering column. In one embodiment the arms are linked by a yoke, and traverse equal arcuate distances in opposite directions relative to one another. In another embodiment the yoke is replaced by a transverse link, with elastomer bushings connecting the link ends to their respective arms. The vehicle operates using the principle of conservation of angular momentum, with the vehicle traveling a sinusoidal path and the operator leaning to the inside of the turn. This moves the center of gravity of the vehicle and operator to the inside of the turn, thus accelerating vehicle and operator along the turning path to increase velocity of the device.
