The SFPD was one of the founding departments in the field of utilizing Police motorcycles (along with their counterparts across the bay in Berkeley).
The unit was founded in 1909, and has grown ever since.
They are officially under the command of the SFPD Traffic Division.
They participate in many duties such as traffic enforcement, patrol, riot control, and special events and escorts.
It is the only fully functional department that utilizes the entire traffic fleet for escorts in the nation.
No other metropolitan city utilizes all its motor bikes for escorts but SFPD.

The entire 43-man unit is based at the Hall of Justice at 850 Bryant Street.
Unlike most cities, they patrol as solo officers (hence the name SOLOS).
They can frequently be seen throughout the city.
The bulk of the unit is composed of Harley-Davidson Road King motorcycles.
There is a separate division called Honda Unit, that is composed of Suzuki DR-Z400S dual-sport motorcycles (which is under the command of the Special Operations Bureau and not the same as Traffic), for city patrol and patrol in and around the area of Golden Gate Park.
Otherwise, every one of the 10 main police stations in the city have 2 motorcycles under their command, used for patrol around their districts exclusively.
