1. A chassis dynamometer (1) for motorcycles with a combustion engine, comprising:
a mounting unit (2);
at least one fastening unit (3);
an operating unit (4);
a control unit (5);
a roller (6) for recording the peripheral speed of a motorcycle rear wheel; and
a flow unit (7), which in turn has comprises:
a drive unit (8);
a diffuser (9); and
an outflow unit (10) arranged downstream of the diffuser (9) in the direction of flow,
wherein the diffuser (9) and outflow unit (10) form a flow channel carrying gas in the operating state, wherein the diffuser (9) is configured to be driven by the drive unit (8), wherein the control unit (5) controls the drive unit (8) as a function of the peripheral speed of the roller (6) in such a way that a speed of the gas emerging from the outflow unit (10) in the operating state is substantially equal to the peripheral speed at least from a peripheral speed of 150 km/h.
