A target system for determining the location of a position on a vehicle comprises a target body, one or more target elements, a trigger, and a point definer. The target elements are disposed on the target body and are detectable by a position determination system. The trigger is positioned on the target body and is remote from the position determination system. The trigger operates the position determination system by selectively changing the detection of one or more of the target elements by the position determination system. The point definer extends from the target body, and the point definer includes a point its a distal end. The point is capable of being located adjacent the position on the vehicle and is at a known location from the target body. The position determination system determines a location of the target body after detecting the target elements disposed on the target body. Methods of using the target system are disclosed.

Methods of using the target system are disclosed. the optically acting surface strikes the first scale is read, and is evaluated in conjunction with the mechanical length measurement between the marking on the optical component and the horizontal marking of the measurement bracket. 10. Method according to claim 1, characterized in that, in order to determine the camber error, the optical component is aimed at the horizontal marking on both sides of the measurement bracket by adjusting the height of the optical component, and in that the respective height setting is read on the first scale, and the difference is related to the distance between the measurement points. 11. Method according to claim 1, characterized in that, in order to determine the steering head offset (LKV), a mean error (MA) in the zero point of the second scale is determined by aiming the optical component at the center of the first scale after which the height of the optical component is moved to the second scale, and the point at which it strikes the second scale is read, and in that the value that is read is corrected by a measurement of the eccentric mounting of the measurement bracket and taking account of any camber error that is found. 12. Measurement device for measurement of a two-wheeled vehicle frame having an essentially U-shaped measurement bracket (12), which can be centered in a retaining hole (5) that is at right angles to the longitudinal axis, can be fixed in a fixed angular position, and has two limbs (13) and an upper crossbar (14), and having an optically acting component (9), which is mounted in a defined position relative to the steering axis (2) of the two-wheeled vehicle frame, in order to form a beam path between the measurement bracket (12) and the optically acting component (9), characterized in that the optically acting component (9) is mounted without any play but such that it can rotate, using an adjustable-height insert (7) which is provided with a first scale, the crossbar (14) is provided with a horizontal marking (18) and with a central horizontal second scale (17), the crossbar is provided with an optically acting surface (16), whose distance from a plane (20), which runs parallel to this surface through the center of the retaining hole (5) is defined, the optical component (9) is provided with a marking which allows a mechanical distance measurement to a marking (18) on the measurement bracket (12) and whose distance from the optical axis (10) of the beam path is defined, the distance between the horizontal marking (18) on the crossbar (14) of the measurement bracket (12) and the center axis of the retaining hole (5) is defined. 13. Measurement device according to claim 12, characterized in that the optically acting component (9) is mounted in or on a headstock (1) of the two-wheeled vehicle frame. 14. Measurement device according to claim 12, having a telescope as the optically acting component. 15. Measurement device according to claim 14, characterized in that the telescope is equipped with a reticle. 16. Measurement device according to claim 12, having a laser source as the optically acting component. 17. Measurement device according to claim 16, characterized in that the laser source in a bar laser or cruciform laser. 18. Measurement device according to claim 12, characterized in that the second scale has a movable vernier and in that the movable vernier is provided with a cruciform marking. 19. Measurement device according to claim 12, characterized in that a further marking is provided on the optical component, which is located at a defined distance from the zero point of the first scale (NPFS) and whose distance from the optical axis in the direction of the first scale is defined.
