Abstract: This universal control method and device for checking the basic geometry of two-wheeled vehicles comprises two aligned pairs of clamping jaws adapted to receive and clamp the rims of the front and rear wheels, respectively, of the vehicle; one pair of jaws is adjustable in the longitudinal direction to suit the wheelbase of the specific vehicle being controlled. The jaws are adjustable transversely and symmetrically on either side of the longitudinal center line of the device, and the base frame of the device is provided with means for adjusting its horizontality. Graduated scales and verniers are provided for accurately positioning the vehicle by taking one wheel, in good condition, of the vehicle as reference.
