Abstract

In order to measure a two-wheeled vehicle frame, in which an essentially U-shaped measurement bracket (12) with two limbs (13) and an upper crossbar (14) is inserted, centered, into a retaining hole (5) which is at right angles to the longitudinal axis, and is moved to a fixed angular position, an optically acting component (9) is mounted in a defined position relative to the steering axis (2) of the two-wheeled vehicle frame, and a relative position between the measurement bracket (12) and the optical component (9) is fixed by means of a beam path between the measurement bracket (12) and the optically acting component (9), the invention provides that the optically acting component (9) is mounted in the headstock (1) without any play but such that it can rotate, using an adjustable-height insert (7) which in 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 mark…
