A couple of police motorcycles that I came across while in Germany a good few years ago. Both are MZs, so I assume that at the time the police were buying machines based on patriotic fervour rather than comfort.
The first is a Saxon 500R with a 500cc Rotax engine, the second is a Skorpion with a 660cc Yamaha engine. Both machines were fitted with special bodywork, police lights, panniers for the radio equipment etc. and a single saddle.
Having owned both machines, of the two options I’d reckon most officers would prefer to have the Skorpion. The vibration produced by the Rotax is probably just a little too harsh. Remember, these guys have to ride about on these bikes all day long.
