In Bremerhaven-Lehe, a police patrol noticed a motorcycle on Wednesday afternoon, April 20, 2021. The rider was traveling along Hafenstraße at around 3:30 p.m. Even when accelerating slightly, the motorcycle was noticeably loud. The Harley-Davidson was stopped.

During an inspection, it was determined that the registration certificate specified a maximum volume of 85 decibels. The police officers conducted a sound level measurement at the station. The value determined here was well over 100 dB. Even an increase of +10 dB is perceived by the human ear as a doubling of the volume.

The vehicle was subsequently seized and presented to an independent expert today. The inspector confirmed the values determined by the police in a further sound level measurement. Because an unauthorized exhaust system was fitted to the Harley, the operating license has expired as a result of the modifications.
