A motorcycle test stand comprises at least one dynamometer configured and arranged to be connected to a drivetrain of a motorcycle to be tested, and a receptacle configured and arranged for receiving a motorcycle frame, and a base fixing the dynamometer and the receptacle relative to one another. The receptable has first and second connecting points configured and arranged to be coupled to the motorcycle frame.

To achieve a compactly designed, simple and robust control valve for a hydrodynamic torque generator which is linear over a wide adjustment range, the control channel () of the control valve is formed in such a way that a substantially linear relationship between valve position (&#x3b1;) and flow ({dot over (V)}) is achieved by rotating the valve body () between a first valve position (&#x3b1;), which differs from the closed position, and a second valve position (&#x3b1;) with a larger flow ({dot over (V)}) than in the first position (&#x3b1;).

A tire test system for tire tests under the most realistic conditions possible, however, including the possibility of widely-varied, simple and precisely reproducible parameters includes a track () contactable by at least one tire, as well as a positive guide () following this track, for example, in the form of at least one rail. In addition, a test trolley () is provided that is guided by a positive guide () and is autonomously driven and/or brakable independently of the tire(s), on which trolley at least one tire () is mountable, and which has equipment for driving and/or braking autonomously and independently of the test trolley ().

For largely automatic determination of the moment of inertia of, in particular, an internal combustion engine on a testing stand, speed n and indicated torque M.sub.M are measured under controlled operating conditions in both a run-up phase as well as in a coasting phase. In order to eliminate the loss moment in the determination of the moment of inertia, the measuring points of the respectively same speed from the run-up phase and the coasting phase are interpreted in combination, this enabling an exact determination of the moment of inertia in a very simple way with the devices that are usually already present at a testing stand.
