.....What are American police doing riding BMW's anyway?
You didn’t expect them to ride Harleys did you?

The police in the city I worked for rode BMW’s for about a year. We had a small fleet of 8 bikes. 6 were used daily, 2 shifts, 16 hours, and 2 were held in service reserve. We ended up selling all of them after a year due to recurring transmission and ring/pinion failures.
The cops then went to the Honda ST1300’s which proved very durable.
However, they did say that they missed the BMW’s agility.
