On March 17, 1941, the Seattle Police Department received eight new motorcycles for traffic and parking enforcement. The new motorcycles were rated for up to 105 mph, but were unable to sustain this speed until reaching 2,000 miles on their odometers. The new bikes joined five others already in use by the department.

In this image, Marion Diedricks skids on a motorcycle to show Seattle police officers what the machine is capable of in expert hands. Diedricks, a motorcycle acrobat and Harley Davidson agency proprietor, sold the new bikes to the Department. Despite his expertise, several of the officers blanched watching Diedricks' high speed demonstration.
